It’s summer in 1976. Changes are happening in the U.S. of A. as it celebrates its Bicentennial. Making a change in their own lives are stockbroker Bruce Miller (Jack Davenport) and his wife, Susan (Molly Parker), who move to a much more posh neighborhood in Chicago. New neighbors Tom and Trina Decker (Grant Show and Lana Parrilla) aren’t quite like anyone the Millers knew in their old neighborhood. The Decker’s open marriage and lifestyle raise the eyebrows of the Millers and their old friends, Roger and Janet Thompson (Josh Hopkins and Miriam Short).
