A documentary about the famous athlete and movie enthusiast who made Serbia's first sound film, Innocence Unprotected. The Nazi occupation of Belgrade prevented the film from gaining wider acclaim. Director Makavejev intersperses clips of the original film with interviews of surviving cast and crew members, as well as newsreel and archival footage.

In 1942, in Nazi-occupied Belgrade, locksmith and acrobat Dragoljub Aleksić wrote, produced, directed and starred in Nevinost bez zaštite, the first sound feature film made in Serbia. It is a thrilling action picture with musical numbers and prolonged sequences of Aleksić's acrobatic stunts. Nevinost bez zaštite was never released due to the Nazi censors. "Gentlemen, I assure you the entire Yugoslavian cinema came out of my navel. In fact, I have made certain inquiries, and I am in a position to state positively that the entire Bulgarian cinema came out of my navel as well."
