The Stones of Light and Perfection - two 500-carat diamonds dating from Moses' time - have been stolen by Nazi war criminal, Colonel Speerman. Speerman orders a freelance assassin to kidnap Isaac Teller, an Auschwitz survivor who's a master cutter of precious jewels. When Teller's niece, Elizabeth, realizes her uncle has gone missing, she hires tough-as-nails P.I. John Shepherd (Chuck Norris) to investigate. Following a bloody trail of murdered jewelers and Interpol agents, Shepherd races the clock to find Teller, for once he finishes re-cutting the diamonds, Speerman will most certainly finish him as well.
