His New York Wife (1926)

Lured to New York with false promises of having her play produced, Lila Lake is forced to accept a secretarial position with Mrs. Julia Hewitt, a dashing young widow secretly married to Jimmy Duval, son of Alice Duval, a prominent society leader. Alice seeks the aid of young lawyer Philip Thorne, who hires detectives to follow Julia; the latter, however, has left town with Jimmy, and Lila has agreed to impersonate her. Thorne, who has previously met Lila, and is unaware of her situation, rescues her from the detectives, and through a misunderstanding they are both arrested and are subsequently disillusioned with each other. Jimmy, however, achieves a reconciliation between his wife and mother, and when Thorne discovers his mistake, he is happily united with Lila.
