Fair Enough (1918)

Ann Dickson's newly wealthy parents become obsessed with breaking into society, but the young misfit is more interested in studying modern slang and wearing outrageous outfits. She tolerates but does not love "Freddie" Pierson, the useless young playboy her parents have selected for her. On a downtown jaunt, Ann slightly injures a newsboy in a car accident and in this way meets policeman Carey Phelan. She invites him on an outing she has organized for the boy and his pals, and the two fall in love. Ann's parents follow her to the picnic, and after a series of misunderstandings, everyone winds up in jail. Carey reveals to Ann that he is actually a millionaire's son who, tired of wasting his life, had joined the police force. The chief of police, an old friend of the Phelan family, holds the outraged parents in custody while Ann and Carey sneak away to get married.
