Mulroney will play Harris, a CIA officer involved in missions to detain and relocate foreign nationals for interrogation. When a political shift in Washington turns his allies into enemies, Harris finds himself the scapegoat for a detainee’s murder and must run from a team of operatives sent to bring him in (McNamara and Coiro), led by a ruthless double agent (Ilonzeh). 

Gibson will star in the movie as an intelligence official running the unsanctioned covert operation to hunt down the disgraced spy.
