VENUS FLYTRAP (1987)

Three street punks--Turk, his girlfriend BB., and his sidekick Wimp--observe two young affluent kids, Ginger and Danny, shoplifting from a record store. On a lark, the street kids invite themselves along to a party at the home of the yuppies' friends, Rod and Arlene. There the party games turn from strip darts to Russian roulette.
