We all need some body to lean on.

Alone on a tiny deserted island, Hank has given up all hope of ever making it home again. But one day everything changes when a dead body washes ashore, and he soon realizes it may be his last opportunity to escape certain death. Armed with his new “friend” and an unusual bag of tricks, the duo go on an epic adventure to bring Hank back to the woman of his dreams.
In Swiss Army Man, consciousness is carried by the dead — a plane of “sentient corpse odyssey”. The story fights on E8/E9 of the E0–E14 reality ladder, compressing consciousness, mortality, love.
