When the barrier to the Waking World is been torn, the Nightmare King invades Brooklyn; the Dream Chasers make their final stand.

The dream chasers are back with a level 7 aberration on their hands: A doom sheep is running amok in Brooklyn! But that's not all – Mateo is neglecting his dream chaser duties and those creepy ravens just won't quit following them.

Frustrated by the loss of their memories, the dream chasers go on a hunt to find the thief. Zoey's convinced the Night Hunter is to blame and ventures to the Grim Realm to track him down, while the rest of the gang finds the Sandman to see if he has any answers.
