Kara Ben Nemai (Lex Barker) is a German adventurer who sets out to find the villainous Yellow Devil who has been terrorizing the residents of Monte Negro. When Kara learns the mystery man is posing as a prosperous carpet merchant, he chases his adversary over the scenic mountains of Yugoslavia. Several gun battles and fist fights occur as Kara tries to capture the criminal. ~ Dan Pavlides, Rovi
