In 1875 a young man, Jack Brennan, from a large and impoverished Catholic family, refuses to be pushed into the priesthood and runs away to become a teacher.
Jack falls in love with Eliza Hewlett, but his dreams and plans are thwarted when his landlord's daughter, Mary Ellen MacBride, falsely accuses him of fathering the child she is expecting.
Rather than be forced to marry his accuser, Jack decides to run away to America with Eliza. Just as the ship is ready to sail Jack is arrested and dragged from the ship, leaving Eliza alone en route to New York with just a few shillings in her pocket.
