The Wild Strain (1918)

Although the prominent Hollywood family prides itself on its illustrious family tree, young Winifred Hollywood exhibits a fondness for wild adventures that greatly disturbs her parents. When Winifred becomes engaged to bank official Harold Burton, his equally snobbish parents visit the Hollywood home and are shocked by the young woman's spirited outbursts and mischievous tricks, and the engagement is broken after she decides to perform bareback feats with a traveling circus. On an evening ride, Winifred overhears two men planning to rob a bank, but when she attempts to phone for help, they make her their prisoner. In trying to rescue Winifred, Harold proves an able fighter, and with the aid of the circus crew, she is freed and the crooks apprehended. The Hollywoods then reveal that one of their ancestors was a bandit, while the Burtons admit that their line included a noted pugilist, and the young people are allowed to resume their romance.
