Amok (1997)

In the 1960's of Malaysia, Natalie is an American on a Peace Corp mission. She meets Wan, a local man, and they become involved. Natalie is wild and carefree, yet very aware of Malay custom and tradition. Wan is very traditional, and has a strong-willed mother who wants him home to marry the girl of her choice. Supernatural elements manifesting themselves in his recurring nightmares compound his sense of guilt for the great sin he has committed. Torn between two cultures, Wan becomes more unhappy and unhinged when he realizes that Natalie has no interest in any commitment. Something's going to snap...
