Theorem (1968)

A wealthy Italian household is turned upside down when a handsome stranger arrives, seduces every family member and then disappears. Each has an epiphany of sorts, but none can figure out who the seductive visitor was or why he came.

Theorem keeps every mind human — it fights its subject at zero distance. The story fights on E8/E9 of the E0–E14 reality ladder, compressing class, sexuality, religion, identity, tradition.
