Someone is watching.
At each abandoned crime scene there's a hidden clue: a tiny metal cog. Someone is sending Detective Sam Berger a message, someone who knows that only he will understand the cryptic trail.
Someone knows.
When another teenage girl disappears without trace, Sam must convince his superiors that they're dealing with a serial killer.

Somebody is killing just for him.
