Hence the two decide to elope from Delhi and travel to get married at Arvind's ancestral haveli in Rajgarh, Alwar, Rajasthan, by road, passing by a desert, in a Tata Safari. After an escape from an aggravated assault, by a mad wayfarer, they bump into a smooth-talking hitchhiker Babu, who is stranded in the middle of nowhere. Babu convinces the young couple to give him a lift. Travelling with Babu proves a nightmare for Arvind and Lakshmi, Babu turns out to be a psychopath. Soon, Lakshmi finds herself hostage of an armed Babu. Thanks to the timely intervention of a truck driver Inderpal and the highway petrol bunk owner, an aspiring actor Bhanwar Singh, Arvind rescues Lakshmi from Babu. After a while, Babu again finds a way, after attacking Inderpal, and re-attacks the couple by haunting them on the road, via Inderpal's truck. But, this time, Babu fails to get hold of the couple.

As the cops are on their way to catch hold of him, he manages to dodge them. On the other hand, the cops suspect Arvind as the serial killer, as he first eloped with Lakshmi, who is D.C.P's daughter. This irresponsible intervention of the cop, who fail to trust Arvind, makes it impossible to chase Lakshmi. Finally, a frustrated Arvind, manages to escape with the cops jeep. The full focus of the police is now on Arvind as they believe him to have committed a murder and dumped the body in a car and that the story of Babu and Lakshmi is a fabrication. Arvind manages to flee to a small bar where he reunites with Inderpal. He and Inderpal now try to track Babu down with the help of Inderpal's truck but are spotted by the police who give a chase.
