Demons are up to mischief to supply Nuksi with human hearts. Once he has five hearts, he can summon his demon goddess Namrael. She demands Mandy's body as a vessel. Luckily, the confused old neighbor Gretel turns out to be a former demon hunter. She wants to help Mandy defeat Nuksi. But Nuksi is already one step ahead of them.
