After her death, Brendan takes it upon himself to solve her murder, enlisting the aid of fellow loner The Brain (
Matt O'Leary) to track information, while feigning to be an inside man for his assistant vice-principal (
Richard Roundtree). His intrusion into the tightly knit circle of high school cliques brings him into the lives of several people, including popular Laura (
Nora Zehetner), prolifically violent Tug (
Noah Fleiss),
stoner Dode (
Noah Segan), seductive play actress Kara (
Meagan Good), athlete Brad (
Brian J. White), and
drug baron The Pin (as in
kingpin) (
Lukas Haas). All are pivotal in his pursuit of the truth of Emily's fate.
