The "half triplets" Barbie, Paul and Ludwig juggle their everyday family madness together. Born to three different women on the same day, they are inextricably linked by father Gerd's involuntary, perfectly timed contraceptive failures.

Paul is the king of procrastinating. Every day he resolves to change his life, but something keeps getting in the way. Be it budding feelings for his ex Berthe, the constant best buddy advances of her new lover Jan or an urgent series episode - Paul always has an excuse ready.

But luckily there is half-sister Barbie, a determined top manager with significantly more balls in her pants, and half-brother Ludwig, a lifer who avoids work like the devil avoids holy water. He constantly intrudes on Paul and drives him crazy.
