Tonya finds herself unclothed and trapped in a barren room alongside thirteen other strangers, realizing she is the last participant in a life-threatening competition. Each person is fitted with a deadly electronic collar, and they must use clues and items from a box labeled “pieces” to uncover both an escape route and the motive behind their kidnapping. As the game progresses, players are systematically eliminated when their “curfew” hits and the lights dim. Every death reveals a new clue, leading them to the chilling discovery that one among them is the murderer. The pressing mystery remains: who is it?
