The expression ';beyond the black stump' refers to the deepest, darkest wilds of the Australian outback, the setting for Nevil Shute's novel of a romance tested by cultural difference. Stanton Laird is an American geologist sent to hunt oil in a remote part of Western Australia. There he befriends the highly unconventional Regan family, the rough-and-tumble owners of a million-acre sheep station, and falls in love with their daughter Mollie. However, when Mollie goes to join him in America, the young couple must face the realization that they are products of radically different worlds.
