Una vez a la semana

Longtime friends Fred Williams, George Drayton, Doug Jackson, and Howard McIllenny are New York businessmen who commute together to and from Greenwich, Connecticut every workday. With the exception of divorced Fred who lives with his mother, they are all married. They have made arrangements with their respective wives to spend Thursday nights in town--their boys' night out--before catching the last train back to Greenwich. They are all feeling somewhat restless in their staid suburban lives and those Thursday nights aren't helping because they haven't yet found anything really stimulating to do. Taking a tip from Fred's boss, the three married men want to rent a "bachelor pad" in the city for weeknight fun with a kept woman. They need the unmarried Fred to be the lessee; he doesn't want to, but out of circumstance he decides to rent them the place and he finds them that kept girl, Cathy, who originally wanted to rent the place herself but decides to stay after meeting the men. Fred likes her and wants to keep her for himself, maybe even marry her. But Cathy's keeping her own secret, which might kibosh the men's plans.
