Savannah Ivey, a veterinarian out on maternity leave; her aunt Margaret, the founder of the Hammond Cat Alliance; and Colbi Stanton, a reporter for the local newspaper take on a cat colony at an old, abandoned building. Odd activity around the place makes them wonder if it actually is vacant; some believe it’s occupied by something other-worldly. When a stranger comes to town and suggests the Alliance open the old building to a fund-raiser, everyone gets involved, including Rags, Savannah’s kleptomaniac cat. He finds something that day that stirs a lot of people-both law-abiding and crooks-into action. Are the feral cats and their caretakers in serious danger? What (or who) lurks inside the old building? What secrets does it hide? And who has the key that unlocks the mystery?
