On a deserted island, Hank Thompson (Paul Dano) is getting ready to hang himself. He then sees the body of a young man (Daniel Radcliffe) wash up on the shore. Hank befriends the corpse, naming it Manny, only to discover that his new friend can talk and has a myriad of supernatural abilities, which may help him get home.
Hank miraculously makes it back to the mainland but then finds himself lost in the wilderness, dragging the talking corpse along for the adventure.
An extraordinary film, fuelled by great performances.
