The Adventurers (1951)

As the Boer War ends a South African soldier hides a cache of diamonds he finds on a body. He returns to the town he left three years earlier where his girl has married a disgraced English officer. Needing funds to get back to pick up the diamonds the Boer enlists the help of a fellow soldier as well as the Englishman and a local hotel keeper. This ill-assorted bunch set off into the bush intent on finding their fortune.
