When a gang from L.A. comes up tranquil Molena Point, California, and begins breaking into the village's quaint shops, Joe Grey's hackles are raised. After all, Molena Point has been the feline P.I.'s home since he was a kitten, and he doesn't take well to marauding strangers. Joe even wonders whether the blonde who's moved in next door to his human companion Clyde could be part of the gang--she's been acting pretty suspicious lately. But when the strangers start trapping and caging feral cats--speaking cats, like Joe and his girlfriend Dulcie--it proves too much for the four-footed detective. He has no choice but to try to stop the crimes.
