Yamla Pagla Deewana, apt to the title, this one brings together the three Deols - Dharmendra, Sunny & Bobby as never featured before in a genre comprising of comedy, action & romance. The film begins in Canada, travels to Banaras and eventually makes its way to Punjab.
The father-son duo of Dharam Singh and Gajodhar Singh (Dharmendra and Bobby Deol) are the biggest con-men in Banaras. Their happy-go-lucky existence involves drinking and pulling off hilarious cons on unsuspecting people. The only hitch in their perfect albeit notorious life arrives in the form of Paramveer Singh Dhillon (Sunny Deol).
A brawny and honest NRI from Vancover, Paramveer, lands up in Banaras claiming to be Gajodhar's elder brother separated at childhood. The duo willingly accepts Paramveer into their fold only to exploit his muscle power to serve their con games.
Meanwhile Gajodhar falls in love with Saheba (Kulraj Randhawa), a beautiful Sardarni from Punjab. As their romance reaches its peak, her brothers arrive and forcibly take her away. Paramveer saves the day with a crazy plan to win the girl back for Gajodhar which leads them to the rustic heartlands of Punjab.
What follows is a roller-coaster ride showcasing the Great Indian Joint Family, Eccentric Relatives, Marriage Mayhem, and a classic case of Mistaken Identities!
