Several years ago, a man was convicted of murder sentenced to the death penalty.
Now 12 people from that trial have woken up in an empty school with collars on their necks. From the prosecutor to witnesses who were never even called on during the case, someone is out for revenge.
But their captor is fair. He's provided them with a way out: Run the Race of the Chinese Zodiac Animals. The winners live. The losers ... well, let's say there's a penalty.
