Brick (2006)

A detective story.

Set in high school but styled like a classic film noir, this captivating mystery follows Brendan, a sharp, solitary student who avoids the usual high school cliques and chaos. His quiet life is shattered when his ex-girlfriend Emily is found dead in a storm drain—just two days after she made a panicked, cryptic call to him from a payphone. Determined to uncover the truth, Brendan teams up with the school’s resident genius, "Brain," and dives into the tangled social web of jocks, stoners, and alluring drama kids. As he digs deeper, Brendan uncovers a sinister underworld lurking beneath the surface—one far darker and more dangerous than he ever expected.
