Good hearted but not worldly-wise, the roly-poly tax inspector, Bharat Bhushan (Vinay Pathak) is back to fulfill his long cherished dream of becoming a singer. To further his ambition he enters a game show hoping to win a cash prize with which he can make his own music album. Eventually Bhushan goes on to win the competition which also wins him a free stay on a cruise ship. It is on this cruise that he meets Ajit Talwar (Kay Kay Menon), an acrid tongued sadistic business tycoon, who is taking sheath on the cruise to flee from the Income Tax department. On the ship, after a string of oddball occurrences owing to a mistaken identity, Ajit Talwar and Bharat Bhushan wind up stranded on a deserted island.
