It's not Lia's day: She is teased by her brother Tim right from the morning. And since her friend Anne is sick, no one walks home with her from kindergarten. Lia accompanies Moritz and Sophie for a while, but at the next corner, they part ways. Suddenly, Lia finds herself all alone on the street. When the nice man with the silver car offers to give her a ride, Lia gets in. At that moment, she completely forgets that she shouldn't go with strangers.
