Firewalker - The Curse of the Volcano 1998

Directed by Rainer Matsutani

A vacation at last for Martin, but he can't quite get a break: things literally "heat up" in the room next door as the lover starts to burn during lovemaking. Martin puts out the fire and saves the couple, but the mysterious incidents continue: the islanders seem to have made a pact with the volcano demon Guayote to heat up the tourists.
