Billy Kuckuck lands right in the boxer milieu with her new enforcement order: The former world champion Kai Burdenski is in debt up to his ears and can neither pay rent nor electricity for his boxing school, a tragedy because he trains teenagers from youth welfare, for whom his rundown hall has become a home. In particular, he has taken under his wing talented young asylum-seeker Samy, who lost her family while fleeing Afghanistan. It doesn't take long for Billy to understand that the "champion" is more than just a coach for Samy and the other youngsters: an enforcement against Burdenski would deprive the young people of this refuge. Therefore, Billy looks for ways and means to help get the boxing legend back on his feet. She turns to his daughter Jessica, but she only saw her father's worst sides at the height of his success, so she wants nothing more to do with him. She distrusts him so much that she even keeps his grandson from him. Billy is no stranger to complicated family situations: her own daughter Hannah, with the help of grandma Christel, is hiding a 5 in maths from her--and that as a preliminary grade to the Abitur. Ex-husband Gunnar and stalker neighbor Holger help Billy this time, both providing decisive assistance in the fight for Burdenski's boxing school. Her biggest problem is getting the champion to accept her help at all; not only is he proud, but he's stubbornly convinced that he must "box" himself out of his misery. For a supposedly saving show fight, Burdenski is even ready to risk his life after he actually quit because of an earlier injury. Billy not only fights against time, she literally fights against death. Will she be able to decide the fight against his will for him?
