While closing his Brazilian Jiu-Jitsu studio one evening, martial arts teacher Mike Terry (Chiwetel Ejiofor) is approached by attorney Laura Black (Emily Mortimer), who is seeking the owner of the vehicle she accidentally sideswiped. Off-duty police officer Joe Collins (Max Martini), who was receiving a private lesson from Mike, sees that Laura is distressed and tries to take her coat. Startled, Laura grabs Joe's gun and it goes off, shattering the studio's front window. To avoid having Laura charged with attempted murder, Mike and Joe agree to conceal the event.
