During the 1960s the Afrikaans radio service of the South African Broadcasting Corporation presented a series on the adventures of a super secret agent, Staal Burger, a character created by the well-known SABC broadcaster Fanus Rautenbach. "STAAL BURGER" had an enormous following among listeners - the rich playboy with an eye for a pretty girl, his fast cars and his straight-punching way with the bad guys. Daan Retief, who played the role of Staal Burger in the radio series, reprises his role for the movie. He is assisted by Staal's sidekicks, Willem (Sarel Breed) and Dada (Miems de Bruyn).
