Mukund and Chaddha spend their days comfortably ensconced in their cushy jobs, wallowing in regrets that make for good conversation. Mukund, in a fit of bravado. resigns to pursue his "calling"; the only hitch is that he doesn't know what it is yet! Chaddha is fired and seeks solace in shooting pigeons at point-blank range.
Mukund's life spirals out of control when Colonel Harpal Singh, the housing society secretary, finds in him a reflection of his estranged son. Harpal places Mukund under "house arrest", puts him on trial in a kangaroo court and coerces him to fight a ludicrous duel.
Constantly under threat, and running out of time and money, Mukund is about to go back to being a man with bad dandruff, a small car and even smaller dreams, when he meets Suman, a girl who, like him, is trying to figure out what life is all about.

Blowfish is a fast, funny and irreverent take on the overhyped pursuit of passion in a country where flashy cars and posh bungalows remain the only lasting symbols of success and happiness.
