Rohit Ray is a financial adviser in Bangalore who literally lives in his boxers. His motto in life is simple. If people find him appealing enough to ask him before investing their money, then its irrelevant of what clothes he wears. His Boss, Raghu and most other people in the office obviously detest his sense of style but don't tell him anything upfront because Rohit can cook delicious fusion dishes and often treats them too. Rohit knows of this soft spot and takes full advantage of this. A Kolkata boy at heart, Rohit's survival system is his mother who helps him whip up these amazing delicacies on Skype with some additional masala of sentimental torture. Rohit has in fact used these cooking tricks more than often to get laid in Bangalore too. Who knew mutton kosha in pasta could attract global women! In fact his colleague and friend Stella is particularly impressed with him. However his happiness is short lived as Raghu, his boss gets transferred and is replaced by a certain Mr. Smith. On the other end our leading lady Sneha Dutta Gupta arrives from Delhi to Kolkata. She is in the city to follow her passion of becoming an interior designer. Rohit tries to impress the new boss with a new recipe. But the moment he enters office he realizes that the entire vibe in the office has changed. He barges into Ragus cabin for a clarification and meets the new boss Mr. Smith! Mr. Smith, the tough cop scorns him for his attire and cooking inside the office and fires him!
Rohit returns the next day to office in his pants to collect his papers. Manjunath, the office peon hands him the supplies that he got the previous day to cook for Mr. Smith. When an emotional Manjunath says bye, Rohit opens his pants and hands it over to him and leaves after saying, Chaddi zindabad Manjunath! Stella tries to make him understand but Rohit tells her that he has other plans. Once back home, Rohit feels miserable. He orders some groceries and invites Stella to dinner. He takes a long shower and cooks passionately. He assures his worried mom that everything is fine. When Stella arrives with a bottle of wine, they drink and smoke up. Stoned and drunk, Rohit makes out with Stella and in a fit of emotional outburst proposes marriage! He thinks that this is the perfect revenge, Firangi ka badla Firangi se! Stella happily agrees and Rohit tells her about his dream of opening a cafe that sells Bengali fusion food. Stella loves the idea and promises to support him. Sneha has a huge fight with her dad about quitting her job. He wants her to come back to Delhi. She disagrees. Popsy, Sneha's masi promises to help her and keep her safe. Later, Sneha sees a couple of properties but doesn't like any of them. The next morning Rohit loses it when he realizes what a blunder he has done by proposing to Stella. He calls up Raghu for help who advises him to go back to Kolkata and to open his cafe and to chase his passion. Rohit isn't convinced. It is only when Stella arrives and declares that they should live together and how she has already informed her family about him does Rohit realize that he has no other option but to flee. The next morning Stella wakes up to find a note saying Sorry. Mr. Smith receives a box full of boxers. Rohit arrives in Kolkata and surprises his parents.
Rivu, Sneha's ex boyfriend, comes and tries to convince Sneha to go back to Delhi. Apparently, her father had called Rivu to request him to convince Sneha to come back. Sneha tells him to go away and blames him for not being supportive. Popsy masi arrives just in time to stop the two from fighting. She warns Rivu that if he ever comes back to convince Sneha, she would not spare him. On the other hand, Rohit's parents try to decode the reasons for his sudden arrival. The mother wants him to marry a girl of her choice, and the father is just curious of his sudden visit. Rohit just enjoys his cutlets and sandesh, and tells them that he's back in town to chill. Rohit's sister, Ranjini, comes back home from school and is pleasantly surprised to see him. They share a smoke on the roof when Billu, Rohit's para best-friend, arrives to meet him. Suranjan declares a party to celebrate his son's arrival. Billu requests Suranjan to allow him to invite his girlfriend, Angika, to the party too. Rohit cooks for the party. During the party, Suranjan announces what a proud father he is. It is at this point that Rohit declares that he has quit his job and wants to open his cafe. A stunned Suranjan drops the bottle of an expensive whiskey and gets super angry. When Suranjan confronts Rohit about his job, Rohit tells him that he has actually been fired because he wore boxers to office. Suranjan tells Rohit's mother, Nandini, that her son needs a doctor. Billu and Rohit get drunk on the roof that night, and Rohit tells him the entire story. Billu promises to help him find the cafe and set everything up, not because its Rohit's passion, but because of the fact that Rohit is a true champ since he has managed to sleep with a firangi.
Angika, Billu's girlfriend helps them in finding a place. Stella keeps calling Rohit and he keeps ignoring the call. Billu and Rohit go and see the property and like it immediately. A similar treatment shows Sneha and Popsy Masi seeing the same property. The landlord tells Rohit that Sneha has already booked the place and he can't do anything about it. Rohit still wants to give it a try and calls Sneha to persuade her. Sneha rejects his proposal immediately and doesn't even agree to meet him once. Nandini decides to help him out and speaks to Sneha on his behalf. Rohit cooks lunch for the entire family and Suranjan makes peace with him after an emotional conversation. Sneha and Rohit meet at a cafe, and Sneha is about to reject his proposal once again, when Rivu walks in. Sneha, desperate to show Rivu that she's moved on, asks Rohit to kiss her. She even agrees to giveaway the cafe in return of this favour. A bewildered Rohit kisses her, making Rivu stop in his tracks.
Once Sneha is gone, Billu and Angika approach Rohit and demand an explanation for the kiss. Rohit declares that Sneha has given up the space to him. Rohit tries to talk to the bank for the loan that he needs to open the cafe, and Suranjan pitches in by saying that he can help with some money. Rohit declines and says that he will manage. Popsy comes home to find Sneha broken and in tears. She comforts Sneha and encourages her to get a new place. She sneaks in a conversation about Rohit too. Rohit and Billu celebrate by rinking whiskey. Billu wants to know how Rohit managed to acquire the space from Sneha in return of a kiss. Rohit tells him that he doesn't know himself and is going out on a date with Sneha to gather more details. Billu is amazed and declares that Rohit is the biggest stud that he has ever met. Rohit feels bad about getting the cafe like this. Billu comes up with the brilliant plan of merging the two businesses. He advices Rohit to open a designer cafe shop with Sneha as the partner. When Rohit proposes this to Sneha, she happily agrees. They both withdraw all their savings and the preparation for the &Bae of Bengal begins. The cafe slowly starts taking shape. Angika and Billu have a fallout because apparently this business merging was her idea, which Billu passed on as his own. Things look almost perfect when Rohit receives a call from the bank. The loan gets rejected!
Rohit and Sneha speak on the phone and try to find out what they should do next. Rohit tells Sneha not to ask her parents for help. A tipsy Suranjan mistakes Rohit as a ghost and beats him up with an umbrella. The next morning, an apologetic Suranjan asks Nandini about why Rohit is at home till this late in the day. Nandini tells him about the loan issue and Suranjan laughs it off and says that he can totally help with it. Billu tries to go and meet Angika to apologise but is turned away by the security guard. Rohit and Billu go to Sneha's place for dinner. Rohit and Sneha get a bit intimate in the kitchen while cooking dinner. Popsy tries to seduce Billu. A scared Billu threatens to call the Fire Brigade. Things get worse in the kitchen too. When Rohit learns that Sneha has approached her parents regarding the money, he is displeased. The night ends on a sour note. Billu and Rohit get drunk on their way back home. Rohit calls Sneha up and apologises. A drunk Billu cant see his friend in pain anymore. He goes and abuses Suranjan for not helping his own son. Suranjan throws him out of the house. Sad and dejected, Billu approaches a guy who was sitting on the pavement and drinking its Rivu. Soon enough, they connect the dots and realise that their sadness is the cause of a common enemy. A Police car approaches them.
Angika calls up Rohit to inform that Billu is apparently missing. When Rohit informs Sneha about this, Popsy Masi takes a keen interest and wants to help in finding him. They all meet up at Rohit's place to discuss what they should do. Nandini and Sneha share a mother-daughter moment in the kitchen. Everyone discusses what should be done. Rohit receives a call on his phone and hears that Billu is apparently in the Police Station, Rivu is also there. They hurry to the Police Station and get Rivu and Billu released with a bit of help from Suranjan. Suranjan asks everybody to come home for dinner. Once the dinner ends, everyone chills around in the house. Billu and Angika get a bit close. Popsy sees this and leaves. Rohit and Sneha get some alone time on the roof. Rivu sees this and leaves too. Rohit receives a call from Raghu asking for the direction of his house. We see Raghu and Stella in a cab approaching Rohit's home.
Rohit and Sneha go out to buy breakfast for the family. When they come back home, Rohit is surprised to see Stella and Raghu in the house. Sneha understands the situation and goes away silently. Stella speaks to Rohit and asks him for the justification as to why he ghosted her all of a sudden. Rohit apologizes and tells Stella how sorry he is. Stella tells him that she has also quit her job and is going back to London. Billu tries to know from Rohit why Stella is back and what deal is happening. Irritated with his antics since the the last couple of days, Rohit shouts at Billu and asks him to go away. Nondini keeps trying to call Sneha but she doesn't pick up. Rohit goes to Sneha's place and tries to apologize. Sneha turns him away. Sad and depressed, Rohit calls up the landlord to cancel the deal. The landlord informs him that apparently someone else has shown interest in buying the space and all their stuff along with it. Rohit gets a bit relieved. Nondini takes Stella out for a walk and tries to understand the real reason for her comeback. Stella assures her that she isn't here to take her son away. Rohit and Stella share a smoke post dinner, where Stella tells him that she came all the way just for a justification and now she was done. The next morning, Rohit cooks breakfast for Stella and comes to the guest room only to find it empty. On the bed is a note from Stella that reads, Don't give up this time. Love.
Angika and Raghu come a bit closer. Raghu flirts with her and tells her of his plans of surprising Rohit by investing in Bae of Bengal. Suranjan asks Nandini about why Rohit is sad. Nandini tells him that Rohit wants to go back to Bangalore. Suranjan is surprised. Nandini tells him to book Rohit flight tickets. Suranjan tells her that he deserves nothing more than a train. Rohit packs his bag and is in a gloomy mood. Billu tries to visit Angika's apartment again and fails. Rohit meets Raghu at a cafe and Raghu offers him a partnership in his new start-up. Surprised, Rohit asks him what start-up it is. A beaming Raghu announces, Bae of Bengal. Rohit and Raghu start getting the cafe ready for inauguration. Billu goes to Popsy's house to say sorry.

The cafe is complete. The inauguration is on the next day. Rohit, Sneha, Angika and Raghu sit down and share beers. A drunk Billu interrupts them and almost picks up a fight with Raghu. Billu insults Rohit too. Sneha tells Rohit about Billu coming to Popsy Masis place and boring her to death with his drunk rants. Angika and Raghu kiss each other and the security guard hands her a flower bouquet which Billu had left for her. Rohit and Sneha come close to each other in the cafe. The next day everybody has lunch together and Suranjan commits to get Sourav Ganguly for the launch. A stop-motion changes into afternoon and then to evening. People starting coming in.
