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.
