Strapped to a gurney with no name, a man wakes in a decaying psych ward. A woman called Ms. Liu gives him twenty seconds to sign a contract for "freedom." Soon he's in a plate-less van bound for a shuttered orphanage with three criminals and explosive headsets. As night falls, signals die, a playground seesaw moves on its own, and a child's diary hints at punishments no one survived. To live, he must report everything?and decide whether the real monster is in the building or smiling behind his own scars.
