The Mystery of Ronggeng Jaipong.

Police Lieutenant Iskandar (Kelly Kalyubi) joins a doctor’s mission to a village but he's really there to investigate the mysterious deaths of several men who were found with snake bites on their necks. The early victims were all men who'd recently had sex with the village "black widow" Wulan (Giselawaty), but then people not even associated with her start turning up dead.
