They can laugh together. They can cry together. They can talk about anything. They spend day and night together, have shared a bed for 23 years. Astrid and Mike actually have the perfect relationship, if they weren't mother and son. Astrid works part-time as a saleswoman in a perfume store. Mike has a 450-euro job in a computer repair shop. Gaming is his passion. But the marriage-like mother-child relationship is beginning to falter: Mike is no longer hungry. For Astrid, it's clear: her son needs help. Kranitz is sure: Mike has a drive jam. He offers the two a special deal: he'll take care of solving their problem in exchange for Mike developing the “KRATING” app, a dating app designed to help Kranitz acquire more customers. But what he hears at the beginning of the next therapy session leaves even the hard-boiled Kranitz speechless.
