When a man-eating cave creature appears with a fortune in uncut diamonds around his neck, Dr. Chambers’ daughter Denae hires adventurers C & C Salvage to find the underground source of the gems. Accompanied by archeaological intern Andrew Paris, mineralogist Prof. Strock, and C&C’s scruffy owners Cort Eastman and Eddy Colchilde, Denea’s hopes of emerging from her famous father’s shadow become as remote as getting out of the caves alive!

Patagonia narrates the journeys of two women – one looking for her past, the other for her future. The film inter-cuts between their stories, in which one of them travels south to north through the Welsh springtime and the other east to west through the Argentine autumn.
