[1][2] Police detective Andreas and his partner Simon are called to investigate an argument in a junkie couple's badly rundown flat, where they discover a child in a wardrobe lying in its own excrement.

The seven-week-old child Sofus is dirty and hungry but after he has been examined by Social Services they realize he is in good health.

Waiting in the hospital's parking lot, he then decides to swap the babies and breaks into Tristan and Sanne's flat, where the parents are sleeping off a high.

Tristan fears that he and Sanne will go to prison and takes their stroller to a busy street, where he pretends that someone has abducted his child from it.

Andreas and Simon, who are ordered to investigate, repeatedly interrogate Tristan and Sanne concerning the whereabouts of the dead baby (Alexander).

After she convinces him to take the baby and keep it warm in his cabin, she jumps into the freezing river, committing suicide.

Andreas reacts with an outburst of rage, hitting and kicking Tristan, whereupon his superior sends him home and orders a meeting with the police psychologist.

At Alexander's autopsy, it is revealed that he died due to a cerebral hemorrhage caused by shaken baby syndrome and that he had several older bleeds and rib fractures.
