One night, Maddie, a young student by day and locksmith by night, gets a call from Claire to open the lock. But the door that the young woman wants to open is not hers, and the bag with which she runs in is also not hers. It belongs to Yannik, a ruthless gangster who accuses Maddy and will stop at nothing to get back the stolen property. Maddy has only one night to prove her innocence and save her skin. What started as an ordinary night shift turns into a brutal transition to violence.
