The diagnosis is a shock. Katharina refuses to accept that her 17-year-old son Basti will be in a wheelchair after a traffic accident. She tirelessly takes him from one doctor to the next, not realizing how Basti feels increasingly suffocated by her care. This changes when Katharina finally meets Janik, a man who understands Basti. In "Sprung ins Leben", Simone Thomalla as a mother has to learn to let go of her son and accept that he wants to live his own life.
