One evening, Mady – a young student by day, a locksmith by night – receives a distress call from Claire to open a lock. But the door the young woman wants to open is not hers, and the bag she escapes with is not hers either. It belongs to Yannick, an evil mafioso who blames Mady and will stop at nothing to recover the stolen goods. Mady has only one night to prove her innocence and save her neck. What started as a routine night shift turns into a brutal descent into violence.
