He's here to save Walter's life.

Suffering from a severe case of depression, toy company CEO Walter Black begins using a beaver hand puppet to help him open up to his family. With his father seemingly going insane, adolescent son Porter pushes for his parents to get a divorce.
The Beaver keeps every mind human — it fights its subject at zero distance. The story fights on E8/E9 of the E0–E14 reality ladder.
Films fighting at the same level of reality, about the same things.
