Metin Müller (Max Mauff) loses his partner and the mother of his one-year-old daughter from one day to the next. From then on he struggles more than well through the daily routine as a single parent. As if that wasn't enough, his mother also tries stubbornly to push back her son's life. "MaPa" tells of the endless, sleepless nights, the balancing act between child and work, the new interpersonal relationships with friends and family, the clichés one is confronted with in everyday life, but also the endless love for one's own child. The tone of the series should be "always honest" - just like life. Sometimes funny, sometimes sad, sometimes dramatic, sometimes completely overexcited. Joyn describes his "Sadcom" as a loving homage to all single mothers and fathers who give their best every day. In this collection of touching and absurd episodes the big questions of life are asked: What exactly is this modern man?
