Jai Courtney is starring as a police officer in the upcoming movie Semper Fi and a trailer was just released.

Cal (Courtney) is a by-the-book police officer who, along with his close-knit group of childhood friends, makes ends meet as a Marine Corps reservist. When Cal’s reckless younger half-brother, Oyster, is arrested after a bar fight and given an unfair prison sentence, Cal – driven by his loyalty to family and fierce code of honor – fights for Oyster (Nat Wolff) in this gripping tale of brotherhood and sacrifice.

Also starring in the film are Finn Wittrock, Beau Knapp, Arturo Castro, and Leighton Meester. You can see the movie in theaters, on demand, and on digital HD starting October 4.
