A tough-talking teen attempts to uncover his ex-girlfriend's killer in director Rian Johnson's hard-boiled high-school noir, told in the style of a Dashiell Hammett mystery. An outsider by nature, Brendan (Joseph Gordon-Levitt) is forced to penetrate the elaborate ranks of the high-school social scene and its more insidious underbelly when the body of his former girlfriend Emily is found lying lifeless in a remote creek. Though the pair had been on the outs, Brendan can't seem to shake the hysterical phone call that he received from Emily the day before her body was discovered, a call in which she rattled off a number of cryptic words: "brick," "pin," "tug," "poor Frisco." He's determined to find the guilty party, and to do that he'll need to uncover the meaning behind her enigmatic phone call.
