Miguel, the dangerous black-clad gunman from Colorado Tempest returns to ride as El Gato to avenge himself against Enrique de Vega, the man who killed his family and stole his birthright. But the stage El Gato stops contains no gold, only his enemy's lovely, young daughter. Kidnaped, ravished, and sent home in disgrace, Elena is forced to marry the portly Diego, who tells her the marriage will be in name only—he will not be sharing her bed. Diego also states that he wants children and urges his bride to take a lover. He sets out to fetch that lover. Shaken by Diego's proclamation and unable to resist the mysterious bandit's lure, Elena seeks comfort and forbidden pleasure in her dark lover's arms, not knowing that El Gato and her stuffy new husband are one and the same.
