Diana is a forty-year-old woman, insecure and introverted. The only source of happiness in her life is her son Christian, a six-yearold boy. She and Jaime, the father, have just separated. One night, egged on by Christian, she honks her car until everyone in Jaime’s building wakes up. After having dodged her for several months, he finally agrees to talk about child support. Christian is playing outside the car. Diana hears the sound of screeching tires and gets a glimpse of a black van taking her son away.
From that moment, both of them embark on a frenzied search. Diana starts losing her mind and reveals her more aggressive side. She wants to plaster the city with missing posters, finds strange ways of making money to keep the investigation going, and does the unthinkable to find Christian. In a surge of panic, she tries to end her life by crashing her car, but the hope of finding her son will keep her afloat until the end.
