20 strangers have been kidnapped by a mysterious killer at an apartment complex, with no idea of where they are.
Left with no outside contact, or no hints as to where they are, the 20 strangers are forced to play the killer's deadliest games. Each game leaves at least one person killed, and everyone is responsible for what they had done.
The 20 strangers must work together to find out who is responsible for this havoc, before all of them are left for dead.
