A recently deceased couple, Adam and Barbara, find themselves as ghosts trapped in their quaint New England home. They are bound to the house for 125 years and are struggling to come to terms with their untimely deaths. While trying to scare away the new living inhabitants of their home—a quirky and obnoxious family from New York City—they discover their own lack of scare tactics. As they navigate the unfamiliar rules and bureaucracy of the afterlife, their attempts to reclaim their home from the eccentric new owners prove fruitless. The couple seeks the help of a handbook for the recently deceased and get to know other spectral entities in the otherworldly dimension.

In their quest for assistance, Adam and Barbara inadvertently summon a mischievous and crude spirit known for his wild, unpredictable, and dangerous nature. The couple is initially enchanted by his promises to rid their home of the new tenants, but they quickly find out that his services come with a high price. As they become entangled in his chaotic methods, which spiral increasingly out of control, they realize they might have bitten off more than they can chew. Concerned for the well-being of the family's teenage daughter, who has the unique ability to see the deceased couple, Adam and Barbara are forced to reconsider their choices and look for a way to rectify the situation without causing further harm.
