What makes a person kill? It's a question true crime buff, Jessica Mills, ponders every day. On the surface, Jessica is your all-American woman-blonde, young, and pretty-but there's something off in her subconscious, something that draws her to horror movies and true crime. Living with a mix of social anxiety and agoraphobia makes maneuvering the world outside of her mother's apartment tough, but her job at the local grocery store is something she can manage. That is, until she gets swept up in the crossfire of an active shooter. In order to survive, Jess must tap into the growing darkness inside of her and cross a line there's no coming back from: committing her first murder.
