He's nearer now, a bearded man in a dark cowboy hat and long dusty overcoat--the Stranger (Clint Eastwood).The Stranger enters the tiny western town of Lago and rides slowly down the main street. The townspeople stop and watch him pass. Freighter Jake Ross (John Quade) cracks a bullwhip to wake his team of horses.
