Mischievous Amit (Sharman Joshi) and shy Jai (Manish Nagpal) are two small town boys who come down to Mumbai for admission in Dhariwal College. To his credit, Amit ends up in a jam when he teases Neha (Raima Sen) and Nisha (Ria Sen) on the very first day of college and manages to drag poor Jai into this mess too. They are brought in front of principal Shalini Devi (Himani Shivpuri) and somehow manage to keep their admission in the college intact. But their biggest problem is that they don't get a room in the college hostel. Not being very affluent, the boys can't just go to a hotel or rent a furnished flat for the duration of college. They employ the help of an estate agent, who finds them a client who rents out a room in her house for cheap, the only condition being: no single men allowed, only families/married couples. Desperate times call for desperate measures. Jai is transformed into Jaya and Amit is the lucky husband. When the tenant couple goes to meet their landlady, they stand dazed to find out that it is their college principal Shalini Devi. Innocent to the con, Shalini Devi agrees to allow this couple in her home. The double whammy for the "couple" arrives when, the next morning, Amit and "Jaya" find out that Shalini Devi has two neices.... The very two beautiful girls they got into trouble with in college: Neha and Nisha.
Now starts the real confusion of romance and love. Amit falls madly in love with Neha but she of course doesn't look at him because according to her he is married. Nisha falls hard for Jai in college without knowing that he is playing wife "Jaya" to Amit. On the other hand Jai refuses to indulge her advances as he wants to sincerely concentrate on his studies and make his parents proud.
The whole college is exasperated with Principal Shalini Devi's autocracy and strictness so both Amit and Jai involve their professor Deepak Verma in a crazy plan. The encourage Deepak to have an affair with Shalini. They think that love can change everything and if Shalini falls for Deepak then maybe she will become softer and loving towards the whole world in general. Amit and Neha coach Deepak in the matters of the heart and love.
The college campus is now ringing with love stories of three couples. Amit-Neha, Jai-Nisha and Deepak-Shalini. And just when these stories are about to reach a happily ever after, comes the climax with a resounding BOOM. Everyone's real identity and real reasons for falling in love are discovered by each other and all hell breaks loose.
The BOOM happens but it does not destroy as expected - The climax shows how Amit wins Neha; how Nisha convinces Jai that love is not a hindrance but rather enhances life and how the strict Shalini finally starts purring like a pussy cat because of her love for Deepak .
Three Bachelors - a story full of comedy, romance and confusion!
