Lewis plays a washed-up German circus clown named Helmut Doork during the beginning of World War II and the Holocaust. Although he was once a famous performer who toured America and Europe with the Ringling Brothers, Doork is now past his prime and receives little respect. After Doork causes an accident during a show, the head clown convinces the circus owner to demote Doork. Upon returning home, Doork confides his problems in his wife Ada, and she encourages him to stand up for himself. Helmut overhears the circus owner agreeing to fire him after the head clown issues an ultimatum. Helmut is distraught. He is arrested later by the Gestapo for ranting about Germany and drunkenly mocking Adolf Hitler in a bar. Following an interrogation at the Gestapo headquarters, he is imprisoned in a Nazi camp for political prisoners. For the next three to four years, he remains there while hoping for a trial and a chance to plead his case.
