After inheriting a hotel from her late brother, a single mom moves in with his good-natured ghost — and high-maintenance guests who will never check out.
“Check in and raise hell.”
2025
Desperate to attract paying customers, Katherine hires an exorcist to get rid of the hotel's ghosts. Ben finds an unexpected soul mate.
Katherine is concerned that a rebellious ghost is a bad influence on Esther. A power outage sends Nathan, Ben and Abaddon into the woods.
While Katherine summons the courage to go out on a date, the rest of the crew deals with a creepy killer who targets lusty teens.
Abaddon struggles to control his instincts, Katherine bumps into a business rival, and Nathan, Ben and Esther investigate a possible werewolf.
Esther's plan to become more popular backfires when she starts a dangerous new trend at school. The hotel's honeymoon suite turns on the charm.
A ghost-hunting reality show films an episode at the Undervale. Ben opens up to an enchanted diary and shares all his relationship drama.
Ben's desire to be more confident spawns multiple personalities. Meanwhile, Nathan keeps falling through floors... but why?
A curmudgeonly relative comes to visit — with no plans to leave. Abaddon is outsmarted by a doorstop, and Esther experiments with raising the dead.
Esther takes charge when soul-sucking demons invade the hotel. Katherine shares a painful truth with Nathan about his death.
The good news? There's a busload of red-cloaked customers who want to stay at the Undervale. The bad news? They might be part of a world-ending cult.
