With sex at it's very best, there's no need for anyone else with Vic and Pat Simone. Even after 30 years of marriage, their heated sex is extremely passionate and very intense. Then, all of a sudden, everything changes.
While on vacation, they meet another married couple whose company they really enjoy, and before long, Vic and Pat are having all kinds of fun with Beverly and Ken Carson. One night, while taking a soak in the boiling hot springs, their fun becomes as hot as the hot springs water when it turns into a swapping of wives.
Because of their torrid four way with Beverly and Ken, Pat not only finds out she likes having sex with other men, she also learns from her lesbian affair with Beverly that she also likes having sex with other women, especially with her husband watching her in action.
Having discovered a new side of his wife he really likes, Vic and Pat look beyond the first couple for others and quickly find themselves a brand new three-way playmate with unhappy housewife Darlene Clanton.
