The satirical mockumentary "Twinfruit: The Can Must Become Human" tells the story of a fictional advertising campaign for canned fruit. In Part I, we get to know Gunnar Kleiber, owner of the advertising agency Kleiber & Partner, as well as the firm’s new Creative Director, Lutz Wolf.

The creative team brainstorms for the canned-fruit advertising campaign — but they all realize that Lutz is the one who’s going to help them level up.

The Kleiber und Partner team is not making much progress with the new campaign… and the deadline is approaching!

There are only 30 hours to go until the team has to present their concept for a new advertising campaign to Hansen, the canned fruit company. Having no good ideas so far, they head to a supermarket to see if they can find some inspiration.

Time is running out, and the team still doesn't really have any good ideas. Finally, Lutz comes up with a concept for the canned fruit ads that they can implement.

The team works through the night and finishes their proposal just in time to get to the meeting in Hamburg. It's clear that Lutz and Mr. Kleiber are thriving on the stress.

Gunnar and Lutz feel that the meeting went relatively well, despite a few awkward moments. Now they have to meet the director, who has been chosen by the client.

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.
