Tony, a successful but illiterate middle-aged grape farmer, sends the photograph of his handsome young foreman, Joe, instead of his own, hoping to woo and marry Amy, a waitress in a San Francisco restaurant. Through a series of letters, the two become close and Tony invites his "future wife" to visit. When the beautiful, young Amy arrives at Tony's Napa, California ranch she falls for the wrong man thinking that Joe is the wealthy Tony. When Tony tries to win her over in broken English, she is at first furious and then charmed. But Tony breaks his legs while showing off to impress Amy, and -- left alone to care for a cripple -- she reluctantly succumbs to Joe's charms and becomes pregnant. Although Tony discovers that he has been cuckolded and that Joe has run off, his anger turns to genuine love and he offers to take Amy back unconditionally for the sake of the child and his own true feelings for Amy.
