Shia LaBeouf is a marine with PTSD in “Man Down” teaser trailer

The first teaser trailer for Lionsgate's "Man Down" has arrived. It sees Shia LaBeouf as Gabriel Drummer, a marine who returns home from war in Afghanistan only to find America is no better than the battlefields he fought overseas and his wife (Kate Mara) and his son (Charlie Shotwell) missing, AceShowbiz said.

The teaser opens with Gabriel telling Gary Oldman's Captain Peyton about his friend Devin Roberts (Jai Courtney). "He's my battle buddy," he shared. "We kicked the doors together we took enemy fire, it's just not a relationship you'd understand if you haven't been through it I guess."

"Is there a reason you don't want to discuss what you saw in that room?" the Captain asks. "What happened in that room is real," he replies. He is seen tearing up as he remembers his past. "I can't take that back. But I can't rewind it," he adds.

Directed by Dito Montiel, "Man Down" is set in a post-apocalyptic America. It centers on former U.S. Marine Gabriel Drummer who searches desperately for the whereabouts of his son, accompanied by his best friend and a survivor.

Written by Adam Simon, the psychological thriller will arrive in U.S. theaters on December 2. It's supported by Toby Kebbell, Clifton Collins Jr., Charlie Shotwell, Jose Pablo Cantillo and Tory Kittles.
