In the tense, politically charged halls of a Washington D.C. high school, a shocking murder shatters the fragile routine of senior Addison Schacht Ansel Elgort. When his charismatic classmate is gunned down in a seemingly random act of violence, the official investigation quickly stalls, leaving more questions than answers. Driven by a deep sense of loyalty and a restless intellect, Addison refuses to let his friend’s death be forgotten. Enlisting the help of his fiercely determined girlfriend, Phoebe Chloë Grace Moretz, he embarks on a dangerous, unofficial investigation of his own. Their quest for the truth pulls them into the city’s shadowy underbelly, a world far removed from their academic lives, where they confront drug dealers, secretive adults, and their own precarious morality. As they dig deeper, guided by a wary teacher David Strathairn and observed by his concerned mother Catherine Keener, Addison and Phoebe discover that in a city built on secrets, uncovering one truth can expose a web of dangerous lies. This gripping drama-thriller, directed by Sacha Gervasi, explores the perilous journey from innocence to experience and the high cost of justice.
