Konstanze is perfect: attractive, mother of two, successful heart surgeon, owns her own home and, unfortunately, has recently started dating her ex-husband. Jacqueline is in her late 30s, a single mother with three children from three fathers, a big mouth with brightly painted fingernails, keeps her head above water with four mini-jobs and is once again stuck with the wrong man. Normally, these dissimilar women would never have had contact. A two-bed room in a rehab clinic becomes a battle zone between the two.
