"Rian X. Mitchell" (Stewart Granger) is an ambitious mining entrepreneur who is looking in Columbia for a long-lost emerald mine built by the Conquistadors in 1687. He finds it but some bandits also find him and he is shot, robbed, pushed off a hillside and left for dead. He manages to stumble away but is then attacked by a jaguar. Fortunately, a village priest named "Father Ripero" (Robert Tafur) happens to be there and shoots the jaguar before it can kill Rian. Father Ripero then takes him to a nearby coffee plantation where "Catherine Knowland" (Grace Kelly) manages to tend his wounds. When he recovers he tells her that he has a partner, "Vic Leonard" (Paul Douglas) that he has to see right away but that he will return. Once he and his partner return to the coffee plantation they begin to work on the emerald mine which creates difficulties for all concerned. Anyway, having given the initial plot I will stop right here so as not to spoil the movie for anyone who wishes to view it. That said, while the entire cast performed in a decent manner the film seemed slow in some parts and lacked energy. Part of the problem may have been that the romance between Rian and Catherine lacked passion. Likewise, the action was solid but not very unique or original. In short, this is a decent movie with beautiful scenery and a capable cast. But with all it had going for it I believe it should have been better.
