Stolen Hours (1918)

During a raid on a gambling establishment run by her father, Cosmo Lester, Diana Lester rescues Hugh Carton, a member of the English Parliament and a candidate for the Cabinet. Hugh gratefully offers Diana a position as his sister's companion, and soon, the two fall desperately in love. Diana's happiness is threatened, however, when she learns that Hugh is married to a woman who will neither live with him nor divorce him. Diana becomes Hugh's mistress for a time, but his afternoon visits with her cause him to neglect his work. To save Hugh's career, his sister urges Diana to leave him, whereupon the unhappy girl returns to her father. She eventually accepts the marriage proposal of her old friend, Phil Duran, but before the wedding, she suffers a breakdown. When Hugh visits her with the news that his wife has granted him a divorce, however, she regains her health and good spirits, and is joined to the man she loves.
