For Marko, life mainly consists of frozen pizzas and back pain. For almost 30 years, the widower has been hauling frozen goods for the company "Eisland" to the front doors of his mostly older customers. When Marko has to take early retirement due to illness, his life gets into imbalance. Thereby Marko has only one goal: his studying son should have it better one day. Lawyer or judge, that would be something. The main thing is no work where you have to wear a name tag. The decease of an old female customer unexpectedly opens up a whole new business model for Marko. Unfortunately, he reckoned without the nosy neighbors. To make matters worse, his own son also finds out about it. Marko's house of cards threatens to collapse. Then he meets his idol Roland Kaiser at the bar.

In the sequel of "Ants in the Pants" we again meet Flo and his friends.
