KHEL tells the story of two thick friends — Dev [Suniel Shetty], a business tycoon, and Rohan [Ajay Jadeja], a simpleton, who lives all by himself.
Rohan comes across Saanjh Batra [Celina Jaitley], an interior designer. Saanjh gets attracted to Rohan's simplicity and honesty and falls in love with him.
In a change of events, Rohan gets arrested on charges of murder. Dev and Saanjh are crestfallen. While Rohan is sentenced to life imprisonment, Dev and Saanjh, while sharing a common grief, become close friends.

Upon investigating Rohan's case further, certain evidences force Rajveer to start thinking that this is no ordinary game. What happens next?
