ISO a Horror Film from 2000's
I'm searching for a horror film that I think was made in the early 2000's. I don't remember the title but I remember some of the plot. Its about a detective hunting a mobster. She tries to infiltrate his gang is shot in the head. At some point, she finds herself on a highway in another dimension. I remember at some point, she comes to a gas station and meets The Highway Man. She also tries to find a kidnap victim. At some point, as the film comes to an end that she figures a way to get her target, the mobster, by playing this whole plot out again and again. Does anyone know the name of this film?
