Two men, a hearse, a corpse, 5 gallons of gas... and a promise. Gram Parsons was one of the most influential musicians of his time; a genius who knew Elvis and the stones and led the Byrds. As fame and fortune came within his grasp, he died unexpectedly in 1973. When Gram's best friend Phil hears the news, he gets busy to fulfill an old promise - to cremate his buddy in the majestic desert wilderness of Joshua Tree. The plan looks great but there are snags... he has to steal the body from under the nose of the authorities, then evade the police, Gram's father and an avenging ex-girlfriend, with only a stoned hippy for company and driving a psychedelic hearse!
