Charlie is always trying to find unusual things to capture on camera and takes a chance photograph in the dark of something swimming in the river.

He thinks he knows what it was, but no one believes him.

When the photo's displayed at school, new boy Peter seems fascinated.

It seems bizarre. But Peter's weird, when he looks at people in a particular way, odd things seem to happen.

As Peter becomes an outsider Charlie gets involved, worried that Peter's being bullied.

Soon Charlie finds himself unravelling a mystery that's too strange to imagine - one that becomes a matter of life and death.
