Trapped in a sleepy Washington town, the detectives take on a local case: helping Crystal's quirky housemate Niko get rid of her paranormal parasites.

The group tries to free a family of spirits from a nightmarish loop inside a haunted house, but it triggers an extreme case of déjà vu for one detective.

The gang looks into a disturbing trend of deaths at a lighthouse. Crystal hears a distinct voice while piecing together clues about the seaside mystery.

While Crystal, Edwin and Charles investigate the tragic murders of two popular jocks, Niko sets up Jenny and her secret admirer on a butcher shop date.

A crisis forces Crystal to improvise on the job as Monty recruits the boys to locate his missing friend — but the eerie case isn't what it seems.
