Marie thinks to return to her job one year after the birth of her daughter Nora. Her husband Holger is already looking forward to two-month parental leave in which he wants to be totally there for her daughter. Her daughter? They rush into an emotional hell without warning. The youth welfare office informs them that their child has been swapped in the clinic. Sandra, the other mother, who has their biological child, is a single-mum student. While Sandra outwardly seems to handle the situation with comparative ease, Marie is completely overwhelmed. Sandra' life situation leads to a dispute with Holger because Marie can't accept that "her daughter" might grow up with a poor single parent. Then the press gets wind of the matter, and there is no turning back: the children must be exchanged.
