Sundel Bolong.

A newly-married woman and former prostitute whose husband, a ship's captain, has gone to sea, is pressured into returning to her old profession. When she refuses, she is violently gang-raped and left pregnant and despondent. She kills herself while attempting to abort the fetus but returns as a vengeful Sundel Bolong, a ghost with a putrid, rotting hole in her back. When the rapists and conspirers start turning up dead, her husband and the police try to put a stop to the violence, once and for all.
