At a quiet high school, Chester is the janitor that everyone trusts and is always watching out, always there when no one else is. But, a single humiliating secret caught on camera at a birthday party, turns him into a joke overnight. As whispers turn cruel and laughter turns violent, an accident silences Chester for good. Or so it seems. Because something wearing a familiar smile refuses to stay gone... the ones that laughed first, just might be the last to stop screaming.
