Nadia and Susanne have just met. They look uncannily alike, practically doppel-gangers, but one is filthy rich, with a husband and a lover, and the other dirt poor and single. When Nadia eventually asks Susanne to spend the weekend with her husband how can she refuse the outrageous fee on offer? Nadia wants to spend a few days with her lover and convinces Susanne that the subterfuge will work. So Susanne changes her hairstyle and clothes and, one Friday afternoon, drives Nadias wine-red Alfa to her beautiful suburban villa with its indoor pool, glass doors opening on to the sloping lawn. What appears to be a harmless game becomes a deadly web of lies.
