During World War II thousands of American servicemen were stationed overseas in various countries. It is in England that American GI Jack Ricker meets and marries an English widow with a nine-year-old son, Thomas. Thomas likes his new stepfather and he's hopeful about their future. But now with the war over, Jack is back in America. Thomas and his mother make plans to leave England and join him. Thomas is apprehensive about moving. He won't know anyone, apart from Jack. In America, they play baseball and not cricket. Will he fit in? Thomas and his mother find themselves on a trans-Atlantic voyage on the Queen Mary, sailing to America and a new life. They're not alone; hundreds of other "Brides and Babies" are on board, making the same trip with the same dreams. When Thomas helps another passenger handle feelings of homesickness, he realizes he is prepared to start his new American life.
