Theorem

A handsome, enigmatic stranger (Terence Stamp) arrives at a bourgeois household in Milan and successively seduces the son, the mother, the daughter and the father, not forgetting the maid. Then, as abruptly and mysteriously as he arrived, he departs. In this cool, richly complex and provocative political allegory, director Pier Paolo Pasolini uses his schematic plot to explore family dynamics, the intersection of class and sex, and the nature of different sexualities.
