## Premise

Impulse follows 16-year-old Henrietta "Henry" Coles who discovers she has the ability to teleport but has no control over her destination. The first time she realizes this, she is in a truck with her high school's basketball captain and star, Clay Boone, who tries to rape her. She has a seizure and teleports, in the course of which she inadvertently crushes much of his truck when her ability to teleport first manifests, leaving him a paraplegic. The show then explores Henry's feelings of fear regarding the assault, and the discovery that those feelings can trigger her ability to teleport.
