Shea Whigham is the only person standing between Olivia Munn‘s single mother, her convict ex, the local crime lord he works for and a ruthless cartel in the upcoming crime thriller The Gateway — and ET can exclusively debut the trailer.

The Gateway stars Whigham as Parker, a tortured social worker who finds himself fighting to protect a client, Dahlia (Munn), after her husband, Mike, is released on parole. Returning to work for a powerful crime boss (Frank Grillo), Mike hatches a plan to steal a drug stash that puts the lives of Dahlia and their young daughter in danger.
