Reyes is taken to hospital after a car accident and falls into a coma. She finds herself in a dark dreamscape with the hospital's other comatose patients. Meanwhile, in the waking world, Doggett suspects that something is not right about Reyes' condition.
This episode contains examples of:
- Adventures in Comaland: While comatose, Reyes finds herself in a dark version of the hospital that is uninhabited except by the other people in her condition, and occasionally by Audrey. She eventually learns that there is a specific action she can perform that will cause her to wake up.
- Character Title
- Deadly Doctor: Dr. Preijers renders his patients braindead and then kills them under the pretense of "Mercy Kill" so he can harvest their organs. He also murders people who find out he is doing this.
- Recycled Script: Has a very similar premise to season 2's "One Breath", with Reyes spending most of the episode having Adventures in Comaland.
- You Look Familiar: Tracey Ellis portrays yet another character like her character in "Oubliette" who has some kind of link with victims of a psychopath and who gives her life so that the killer might get caught.
