Catwoman

Liquidated after discovering a corporate conspiracy, mild-mannered graphic artist Patience Phillips washes up on an island, where she's resurrected and endowed with the prowess of a cat — and she's eager to use her new skills... as a vigilante. Before you can say "cat and mouse", handsome gumshoe Tom Lone is on her tail, fascinated by both of her personas.
