Lutz and the director Adrian Kosinovic talk about and clash over the production of the commercial. Adrian tells us what fascinates him about his work, and we also get to see some of the casting process.

Although many of the actors go home disappointed and even humiliated, two lucky ones get cast as a strawberry and an orange. Meanwhile, Gunnar has some bad news for Lutz regarding the client.

Lutz Wolf and Mr. Kleiber have now definitely convinced Hansen himself of their campaign. Now it's time to get down to the real work. Lutz and Adrian first want to see how mankind's inner banana has been brought to life in the form of a costume.

The representatives from Hansen and Gunnar's team meet to discuss all the steps that need to be clarified before production. There seems to be general agreement on the idea, but it's not without some tense moments.

Here we witness the crew's extensive preparations for the Twinfruit shoot and see Strawberry and Orange in action. Ms. Gerstenberg and Mr. Müller from the Hansen company are most impressed by what they see.

The shoot seems to be going really well until a problem suddenly comes to light, and Lutz and Adrian immediately blame each other. Can they work it out before the client notices?

Now all that's missing is the music for the commercial. The agency has brought in the experts to produce a suitable rap with children. And Mr. Hansen finally makes a personal appearance to see the results.

The commercial has been shot and is now ready to be edited. Mr. Hansen has also come to see the results, accompanied by Ms. Gerstenberg. The look on his face speaks volumes...

To everyone's surprise, some last-minute adjustments are made to the commercial. But they should have known that Hansen was always going to have final word.
