Banshee (2006)

A kick-ass professional car thief, Sage, (Taryn Manning), steals a classic '66 Charger on a challenge. It turns out the car belongs to a serial killer (is there another kind?), who proceeds to slice and dice her friends because he wants his car back, and wants Sage dead. Sage also deals with treacherous fellow criminals, and a cop who wants her in jail, or wants to start a relationship (he hasn't decided yet).
