Two brothers, Hugh and Dan Clayton, love their father's secretary, Phyllis Jones. She chooses Hugh, and they marry before he goes to war as an airplane pilot. Shot down in France, he loses his memory and becomes a drifter. Eight years later, Phyllis, resigned to her fate, promises to marry Dan after a visit to the place in France where Hugh was last seen. Meanwhile, Hugh, back in America, is working at his father's aircraft plant. While he is test-flying an airplane, his memory returns. He crashes and is taken to an asylum because of his insistence that he is Clayton's son. He escapes the asylum, steals an experimental trans-Atlantic airplane, and flies it to Paris to be reunited with his family.
