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.

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.

Crystal reckons with the past after memories come rushing back. With Esther's evil scheme underway, the group is forced to face their deadliest foe yet.
