One evening, Mady – a young student by day, locksmith by night – receives an emergency call from Claire to open a lock. But the door the young woman wants to open isnโt hers, and the bag she runs away with isnโt hers either. It belongs to Yannick, a vicious mobster who blames Mady and will stop at nothing to retrieve his stolen goods. Mady has only one night to prove her innocence and save her neck. What started out as an ordinary night shift turns into a brutal descent into violence.
