A technical glitch sends rocket pilot Os (Rolf Ludwig) from the year 2222 back to 1960 – naked and without any money. A 24-hour stay in East Germany brings a number of adventures for him, as well as for the people he meets.
First Os is mistaken for famous actor Martin Marten. Then, because his Feelings and Thoughts Objective Lens allows him to read minds, he can't resisted getting involved in other people's problems. By the time the technical problems are straightened out and Os can return home, he has become convinced that the people of 1960 are not mature enough to handle the Objective Lens.
