One evening, Maddie – a young student by day, a locksmith by night – receives an urgent call from Claire to open a lock. But the door the young woman needs to open is not hers, and neither is the bag she is fleeing with. It belongs to Yannick, a vicious thug who blames Maddie and will stop at nothing to get his stolen goods back. Maddie has only one night to prove his innocence and save his neck. What started as a routine night shift turns into a brutal descent into violence.
