The Key

This erotic outing by Tinto Brass (CALIGULA) is based on the novel by Junichiro Tanizaki. Husband and wife Nino and Teresa attempt to revive their sex lives by each writing their most intimate fantasies in separate diaries. A series of resulting sexual adventures liberates them from their tired routines--but at a great cost to Nino, who is 18 years older than his wife.
