Adapted from a novel by Laura Kasischke, this gauzy drama by Vadim Perelman (House of Sand and Fog) is an unfortunate combination of real-life horror and narrative game playing. A high school shooting rampage culminates in two friends (Evan Rachel Wood and Eva Amurri) being held at gunpoint by a deranged classmate, who threatens to kill one of them; from there the movie cuts back and forth between the girls’ friendship leading up to the crisis and events 15 years later, when Wood has aged into an emotionally damaged Uma Thurman. Perelman never overcomes the disjuncture of having two familiar actresses play the same grown character, and despite the endless crosscutting, the two halves settle respectively into ghoulish foreboding and murky psychological drama. R, 90 min.
