Summary Chloe makes a guest appearance on a series of late-night radio shows about psychology in daily life. Among the callers, on a range between eccentric and totally nuts, is one woman who introduces herself as Caroline; in a trembling voice, she explains that she is afraid of her husband, who is becoming more and more violent. As Chloe encourages her to go to the police and talk to social services, we suddenly hear a man's voice behind her. Caroline screams and lets the telephone fall. We hear the noise of blows and screams, then silence. The media seize this live public crime and brandish it as a flag symbolic of the fight against domestic violence. Chloe convinces the Attorney General to open up an investigation, and the team scrambles to make best use of the scant evidence they have to find Caroline, hoping she is still alive. But when a series of strange roadblocks stunt the investigation, they can't help but ask themselves the uncomfortable question: does this woman really exist?
