When 73-year-old Jen decides to marry Eddie, a man she's known less than two months, her four aqua aerobics friends, whom she's known for about 6 months, are surprised but supportive. They take her out for drinks to celebrate, but when Eddie decides to have a "stag" party in Las Vegas with his son, Jen's friends plan a five-day "hen party" trip to Paris.

The story revolves around the five women and how they view life, love and marriage. Jen and Rose are widows. Jen thinks marrying Eddie is a good idea because she's lonely and wants a companion. Rose is a pianist whose life with her late husband, Bernard, had its ups and downs. Rose realizes she's become stiff and boring. Della and Tess are married; Della happily to free-spirited Sylvester and Tess to grumpy, critical Alan who would rather golf than talk to his wife. Pam is single and always has been - the love of her life is her cocker spaniel, Elvis.
