Warm Water Under a Red Bridge

Yosuke (Koji Yakusho), who was once a successful businessman, is out of work and separated from his wife.

When an old friend tells him of a golden Buddha hidden in house in a remote fishing village, Yosuke travels there to retrieve it, but gets more than he bargained for.

The treasure is indeed hidden - and he discovers it in the powerful sexual response of a young woman who lives in the house with her aged grandmother.
