As the world teeters on the brink of World War II, 10 strangers are invited to isolated Soldier Island. Among them are young secretary Vera Claythorne, soldier Philip Lombard, General John MacArther, spinster Emily Brent, and Judge Lawrence Wargrave. With seemingly nothing in common, the guests wonder who their mysterious host may be. But the ominous reason for their visit soon becomes clear…and by the end of the night, the first of them is dead.
