Cue the disco! Swingtown, about the lives of three couples living in the sexy, suburban ’70s, premieres Thursday (10 p.m. ET) on CBS. In the new drama, Susan and Bruce Miller (Molly Parker and Jack Davenport) move to an upscale neighborhood in suburban Chicago in the summer of 1976. There, they meet Tom and Trina Decker (Grant Show and Lana Parrilla), couple who love to show off their liberated lifestyle. The Millers are tempted by their new neighbors but also don’t want to alienate their old friends, the conservative Janet and Roger Thompson (Miriam Shor and Josh Hopkins). Watch a preview clip.
