His Last Race (1923)

Carleton goes off to the mountains after failing to win Mary, who fancies herself in love with another whom she marries. Carleton and some newly-found friends establish a health resort to make money and Mary, a widow, after a time brings her small son there to regain his strength. Carleton's enemies plan to get hold of the property and try to steal his horse before the race, but Carleton is too clever for them and succeeds in saving the race, the property and winning Mary.
