Film opens showing German astronomer, Erwin Finlay-Freundlich, who designed the solar telescope housed in the Einstein Tower observatory. He poses in a white laboratory coat (without his glasses) and then steps away to put them on and climb steps leading the way to the tower. The unusual building sits in a park-like setting on the Potsdam Telegraph Hill and contains Finlay-Freundlich's solar telescope for observations related to the theory of relativity. (Although he did not work at this facility, Einstein endorsed its construction and mission. In his honor, it is named the Einstein tower, aka Einsteinturm.) The remainder of the film shows various views of the observatory.
