Väter allein zu Haus: Mark

Gerd has three children from three different wives. He also owns a small craft business. But he has promised Michaela that he will look after their daughter Laura as soon as she starts school. This allows Michaela to resume her work as a nurse. The condition for Michaela accepting Gerd's marriage proposal is that he takes on this task and fulfills it responsibly.

Timo is in his late 20s, a former Bundesliga soccer player and has fallen from grace. He has been known as the "disgrace of Altona" ever since he botched a penalty kick in a cup match. After countless escapades, his professional career is over. He now earns his living as a bouncer in a bar. But his family situation is much worse than his professional downfall: his ex-wife Nicki is now living with Robert, his ex-manager. He only sees their three children Tom, Luis and baby Lilly three days a week.

Andreas finds it difficult to come to terms with the fact that Stella, his husband Christian's niece, is becoming more and more independent at the age of seven. Stella has lived with the two men since her mother's early death. Andreas looked after her lovingly every day, which is why he has never worked, despite having completed an engineering degree. And now, as a full-time father, should he no longer be in demand and find an employer that his vita doesn't put off? Difficult. His father Herbert has never made a secret of the fact that he doesn't believe in his son's life model. The fact that the grumpy pensioner was kicked out of the door by his wife Liselotte after more than 30 years of marriage and is now moving in with Andreas and Christian of all places, harbors potential for conflict.
