A veteran inmate takes a young criminal under his wings in the first trailer and new poster for the crime thriller Son of a Gun, starring Ewan McGregor and Brenton Thwaites.

In the criminal world, life is like a game of chess. To gain control, you have to stay a few moves ahead of your opponent. Lose that control, and you risk becoming a pawn in their very dangerous game. During a six-month stint inside a West Australian prison, rookie criminal JR (Brenton Thwaites) meets the smart and enigmatic Brendan Lynch (Ewan McGregor). In exchange for protection on the inside, JR agrees to help Brendan get outside, hooking up with the influential Sam Lennox (Jacek Koman) to orchestrate a daring prison escape that frees Brendan, and inmates Sterlo (Matthew Nable) and Merv (Eddie Baroo).

JR is rewarded for his efforts, and with a taste of the high life and flirtations with Sam's beautiful girl Tasha (Alicia Vikander), he gets sucked deeper into Brendan's criminal world. But whose game is he playing? Becoming a father-like mentor to JR, Brendan convinces him to join in on another high stakes job - robbing a Kalgoolie gold mine. But with millions of dollars at stake, it's hard to tell whom JR can trust, and whose side each player is actually on. And with his feelings for Tasha increasing, and his faith in Brendan decreasing, JR must figure out his next move... before its check, mate.

Check out the trailer and new poster for Son of a Gun, which will be available exclusively for DirecTV subscribers starting December 11, before it arrives in theaters January 16, 2015 from A24 Films.
