Alan (Cameron Daddo) and Wendy (Brandy Ledford) Barnet are a normal, everyday couple whose outwardly perfect marriage has one problem - they are bored with each other in bed. Self-help books, counselling and even sex shop toys aren't working. An ad placed in a swingers' magazine leads them to Zebra Lounge and a couple of experienced swingers - Louise (Kristy Swanson) and Jack (Stephen Baldwin) Bauer, who definitely walk on the wilder side of life.

What begins as an anonymous erotic rendezvous explodes into an electrifying experience that is beyond their wildest imagination. The spark is back in the Barnet's marriage, but they agree - once is enough. However, the Bauers disagree and they begin weaving a clever and diabolical web of intrusion and coercion, pulling Alan and Wendy deeper into their lives. The Barnets soon realise that they risk more than public exposure if they don't continue the sexual liaison. Jack and Louise play a far deadlier game.
