Amanda Nelson (Meredith Baxter) and her best friend, Joan Bixler (Swoosie Kurtz), are happy suburbanites until a lurid affair involving both their families upsets their domestic ease. Dana (Clare Carey), Joan's daughter, begins sleeping with Rob (John Terry), Amanda's husband, and the revelation of this romance dredges up long-buried jealousies and grudges.
