Nadia and Susanne have just met. They look uncannily alike, but one is filthy rich and has both a husband and a lover while the other is dirt poor and single. So, when Nadia asks Susanne to spend a weekend with her husband, how can she refuse the outrageous fee on offer? So Susanne changes her hairstyle and clothes and, one Friday afternoon, drives Nadia's wine-red Alfa to her beautiful suburban villa. However, what appears at first to be a harmless game quickly turns into a deadly web of lies.
