POSSIBLE SPOILERS: Charlie Sheen plays a cop going undercover in a biker gang. The point of the film seems to be that Sheen's character loses himself in his undercover role and becomes unsure of who he really is. There is some exposition about him being abused as a child, but it really doesn't ring true. Sheen performs very well and is almost believable except that he lacks the size to carry off the biker part. Linda Fiorentino is excellent scenery here, as always. Grade: C+
