A killer with one rule. A witness who refuses to play by it.
A serial killer leaves a chilling note on the bodies of his, "They should’ve kept their mouth shut." His rule is simple; whoever reports the body of his last victim becomes his next target. But when Alyssa stumbles upon the crime and refuses to report it, she becomes his obsession.
He can't kill her, it's against the rules… but he can't let her go, either. Instead, he starts toying with her mind, pushing her to the edge.
In a deadly game of survival, one question
Who will break first? The killer or Alyssa?
