Wonder Woman and Steve Trevor stop the Cheetah and her gang from robbing a zoo of its priceless extinct animal exhibit for a client. But the Cheetah escapes, and later hypnotizes Trevor into smooching with her! When Wonder Woman sees them, as the Cheetah had planned, she is tear-stricken and upset, allowing the villainess to take her by surprise, steal her magic lasso, and encircle her with it. Wonder Woman, enslaved by the Cheetah, is forced to take her and Steve to the Cheetah's private island.
