The main character, Gisbert—played by Hape Kerkeling—is an employee of a temp agency who takes on a different job in each episode. Due to his clumsy and awkward nature, he inevitably fails at every task. At the end of each episode, his trademark line is: “I only wanted to help!” Gisbert appears to have no last name and is always referred to by strangers simply as “Mr. Gisbert.”
