In the aftermath of a mysterious tragedy, the students of Sacred Heart High just want things to go back to normal. But their Nightmares, reality warping monsters created from fears, problems, and trauma, are wreaking havoc on the school community, making a normal life impossible. Students are taking Nightmare fighting into their own hands, even at the risk of expulsion or arrest.

As the infestation grows, the God of Dreams reaches out to 6 students for assistance, promising to help them solve the mystery of their deaths as long as they keep fighting the monsters---
But will they be strong enough to face their own worst Nightmares?
