In the early '80s, Detroit 14-year-old Rick Wershe, Jr. (Richie Merritt) proved a fast study under his low-rent gunrunner dad (Matthew McConaughey), and his growing notoriety in the inner city caught the attention of the FBI-who'd in turn recruit him to infiltrate and inform on the operations of the local drug czar (Jonathan Majors). The bizarre odyssey that followed propels this striking true-crime opus; Bel Powley, Jennifer Jason Leigh, Rory Cochrane, Bruce Dern, Piper Laurie, Eddie Marsan also star. 110 min. Widescreen; Soundtrack English.
