Country-rock pioneer Gram Parsons (Gabriel Macht) and his friend and road manager Phil Kaufman (Johnny Knoxville) have a pact: Whichever of them dies first will be cremated, and the ashes will be spread in Joshua Tree National Park by the other. When Parsons dies suddenly at 26, Kaufman feels guilty for not having done more to save his friend's life, but he intends to keep his end of the bargain, even if it means stealing Parsons' corpse and outrunning the cops to do it.
