When her husband Jan admits his advertising agency is bankrupt, product designer Katrin is faced with two choices: either they move out of their comfortable home or she must take an unrewarding job designing new sanitary facilities for a luxury hotel. The burden of her job, kids and household quickly becomes too much - until Katrin discovers a website offering free testing of high-tech household androids, complete with a user-customized appearance and speech capabilities. Katrin secretly orders one, and is stunned to find the android is her exact mirror image! At first, the android "Kate" functions perfectly, with her family truly believing it is Katrin. Suddenly, the android begins misbehaving. Although her irritation grows, Katrin's kids are delighted: they have never seen their mom act so cool! Although "Kate" does wreak havoc in Katrin's world, the android's misadventures also cause Katrin to realize how much her own perfectionism affects her family. Once she recognizes "Kate's" advantages, she reconciles with the android, but now "Kate" wants to be deactivated - too much input.
