The Naked Jungle (1954)

It’s 1901. At 19, tough, stubborn Christopher Leiningen came to South America and built levees to claim thousands of acres of Rio Negro river land for a chocolate plantation. Now 34, with no knowledge of women, he recruits a mail-order bride in New Orleans. She’s beautiful, independent, and arrives ready to be his stalwart helpmate; however, no one has told him she’s a widow. He rejects her. During the next week, as she awaits the boat to take her back to the US, they learn that legions of army ants will strike in a few days’ time. She joins the fight to save the plantation; their courage and his probable loss of all he’s worked for may crack his resolve to send her away.
