The Gift #9

Vannie and her friends regularly hang out in an abandoned house, smoking joints and having sex. But one night a police raid hits the wrong house and all of Vannie's friends are killed while she hides behind a counter. Vannie tries to escape when she encounters the Ancient One. He says she must either accept his 'gift' and extract vengeance or join her friends. As the police close in she accepts his 'gift' (in the form of a joint). Vannie temporarily turns into a smoke-like wraith and kills the leader of the corrupt police unit.
