Set in the coffee fields of Colombia, Green Fires stars Stewart Granger and Grace Kelly. Granger plays emerald prospector Rian X. Mitchell, who intends to explore an old deserted mine despite the protests of his partner Vic Leonard Paul Douglas and the threat of death at the hands of local bandit El Moro Murvyn Vye. Ms. Kelly costars as Catherine Knowland, whose coffee plantation lies at the foot of the mine where Mitchell labors away. Such natural disasters as rain and flood, coupled with such man-made weapons of destruction as guns and dynamite, continually thwart Mitchell’s search for riches.

Two fishermen pick up a psychotic escaped convict who tells them that he intends to murder them when the ride is over.

Fred C. Dobbs and Bob Curtin, both down on their luck in Tampico, Mexico in 1925, meet up with a grizzled prospector named Howard and decide to join with him in search of gold in the wilds of central Mexico. Through enormous difficulties, they eventually succeed in finding gold, but bandits, the elements, and most especially greed threaten to turn their success into disaster.
