Impulse follows "16-year-old Henrietta, aka Henry, who discovers she has the ability to teleport. The first time she realizes this, she is in a truck with her high school’s Golden Boy, who tries to rape her. She has a seizure and teleports, in the course of which she inadvertently crushes him, leaving him a paraplegic." The show goes on to "explore Henry’s need to reconcile what her assaulter tried to do with the consequence, and her feelings about discovering she can teleport with her feelings about the assault."
