The film tells a fictionalized version of the Pilgrim (Plymouth Colony)' voyage across the Atlantic Ocean to North America aboard the ''Mayflower''. During the long sea voyage, Christopher Jones (sailor) (Spencer Tracy) falls in love with Dorothy Bradford (Gene Tierney), the wife of William Bradford (Plymouth governor) (Leo Genn). The love triangle is resolved in a tragic way at the film's conclusion. Ship's carpenter John Alden (Van Johnson) -- said to be the first person to set foot on Plymouth Rock in 1620—catches the eye of Priscilla Mullins (Dawn Addams), one of the young Pilgrims following William Bradford. Alden ultimately wins Priscilla in another, if subtler, triangle with Miles Standish (Noel Drayton). Lloyd Bridges provides comic relief as the first-mate Coppin, and child star Tommy Ivo gives a touching performance as young William Button, the only passenger to die on the actual voyage across the storm-swept Atlantic, who, according to this film, wanted to be the first to sight land and to become a king in the New World. “I’m going to be the first to see land. Keep me eye peeled, I will. Then I’ll be the first. It’ll be like the Garden of Eden and I’m going to be the first to see it”.
