Hesus Resurreccion, a total scaredy cat who lives with his social-climbing aunt and two rowdy cousins, inherits an abandoned mansion. Coincidentally, the said location serves as a portal to the afterlife for the stranded ghosts, and they know that Hesus is "The One" who would open it. If he didn't, the ghosts would turn into cockroaches.
