Being stranded on a deserted island leaves young Hank (Paul Dano) bored, lonely and without hope. As a rope hangs around his neck, Hank prepares to end it all, until he suddenly spots a man (Daniel Radcliffe) laying by the shore. Unfortunately, he is dead and quite flatulent. Using the gassy body to his advantage, Hank miraculously makes it back to the mainland. However, he now finds himself lost in the wilderness, and dragging the talking corpse named Manny along for the adventure.
