The atmosphere of the classic film noir whodunits of the '30s and '40s is shifted to the world of modern-day Southern California teens in this clever, offbeat thriller. When his ex-girlfriend turns up dead, a high school loner (Joseph Gordon-Levitt) takes it upon himself to solve her murder, immersing himself in the local criminal underworld in the hopes he can flush out the killer. Lukas Haas, Nora Zehetner, Emilie de Ravin, and Richard Roundtree star. 110 min.
