On a Connecticut farm, James Mayo's two sons both love Ruth Atkins. Robert, the younger son, is sickly and dreams of escaping to a romantic life somewhere "beyond the horizon." Andy is hard-working and steadfast and loves his brother deeply. When Ruth reveals that she loves Robert and not, as everyone believed, Andy, Robert's plans to go to sea with his uncle are disrupted. He decides to stay at home and marry Ruth, while Andy, unwilling to remain close at hand as his brother marries the girl he loves, takes Robert's place on the voyage. This turn of events leads to heartache and tragedy for everyone involved.
