Welcome to your nightmares. Fourteen year-olds Esteban and Tristan have a special after-school job. They enter Tristan's father's Sleep Clinic where they have one goal: help people get rid of their worst nightmares. With unique equipment, the Nightmare Brigade can literally infiltrate their patients' nightmare to seek its root and destroy the cause. Things are shaken up a bit, however, when they meet the young sleep study patient Sarah. Esteban thinks he has seen her before... but why are his memories all fuzzy? But the Nightmare Brigade is in jeopardy of getting stuck inside a nightmare forever when a rogue patient, with tragic ties to Tristan's family, hijacks a nightmare they are trying to fix. Will they help avoid a breakdown in their patient and return to the real world? Or is this one nightmare no one wakes up from?
