The Loch

A grisly prank at the loch leads to a dark discovery that takes Detective Annie Redford from working a vandalism case to investigating her first murder.

Forensic Psychologist Albrighton and Detective Quigley press suspects for answers. Taken off the case officially, Annie follows up on her own lead.

Panic grips Lochnafoy after a teen vanishes. Annie helps run a village-wide handwriting test that Albrighton believes will identify the killer.

Albrighton urges the team to act when handwriting evidence points to a local suspect. Annie's husband Alan makes a discovery that puts him at risk.

Dr. Marr's secrets come to light, a key witness is nearly shot and Alan makes a startling discovery.

When a body is pulled from the Loch, Annie trusts her gut to follow a critical lead the others missed — but the clock is ticking to find the killer.
