In a quirky and gothic town where the supernatural coexists with the mundane, a newly deceased couple discovers their beloved home is under threat by a flamboyant yet obnoxious real estate developer, Delia, who intends to transform it into a modern art exhibit. Desperate to save their sanctuary, the couple turns to a mysterious book of the recently deceased, unearthing the existence of an "exorcist" for the living. Enter Betelgeuse: an unruly, chaotic spirit with a knack for mischief and mayhem. Despite warnings against summoning him, the couple believes it's their last hope to halt Delia’s plans and scare away her family.

Chaos ensues as Betelgeuse’s antics spiral wildly out of control. Delia's goth daughter, Lydia, becomes an unwitting mediator between the worlds of the living and the dead, revealing her ability to see and communicate with spirits. As she forms a unique bond with the ghostly couple, she becomes embroiled in their spectral chaos and her family's impending doom. Meanwhile, Betelgeuse's power and appetite for mischief grow, threatening everyone around him. The rejection of conventional ghostly rules thrusts Lydia into an interdimensional showdown filled with strange creatures and surreal landscapes. Allies need to be forged and trust rebuilt as Lydia and the ghostly couple grapple with who is truly haunting whom. Through an unlikely alliance, they navigate a bizarre world where friends become foes and every choice could shatter the boundary between life and the afterlife forever.
