Nick is excited to earn money by pet-sitting for the residents of the Hillside Apartments. What could be easier than feeding cats and walking dogs? But he wasn't expecting an Airedale twice his size... or a hissing, sharp-clawed cat named Eloise. And he's definitely not prepared for the strange happenings at the apartment building: light bulbs that mysteriously burn out, gasoline stored near flammable materials, and two small fires. Can Nick figure out what's really going on before it's too late?
