Home alone for the weekend, Aiden is spending his night just the way he wants. Joking around with his best friend. Eating popcorn for dinner. And watching horror movies all night. But his great night gets cut short when he realizes his neighbor might be a slug demon, a monster who crawls into people's brains and controls their minds. Aiden buys pills online that help him see and smell slug demons. With the help of his new abilities, Aiden will find out once and for all who is a slug demon, but he might not be ready for the truth.
