Seven liars in the circle. Only one can survive...
Seven teens arrive for a school retreat - only to find an abandoned motel and a sinister text message waiting for them: I know what you did a year ago.
Each of the seven buried a guilty secret about their tragic school fire. And now someone is out for revenge.
Every hour they must choose the guiltiest one among them to cross over the white line that circles the motel and be killed. Otherwise, they all die.
