Swift Shadow was one of several FBO programmers built around the talents of Rin Tin Tin clone Ranger the Dog. Trained to obey his evil, sadistic master, Ranger's loyalties are rent asunder when he befriends a much nicer gentleman. The dilemma deepens when the mean master, a professional criminal, uses the dog as an "accomplice." When villain and hero meet, Ranger is ordered to tear the "good guy" apart. He doesn't, as if there was any doubt. Unlike the Rin Tin Tin pictures, Swift Shadow does not strain audience credibility: Ranger looks and behaves like a normal dog, rather than a four-legged human being.
