The Mask (1918)

Billy Taylor gives a million-dollar party. It isn't worth the million, for it isn't much of a party, but the merrymakers mistake Billy's rich uncle for someone else and he cuts Billy off with $50 and leaves the rest to Sally Taylor. Sally promptly throws over her carpenter-sweetheart and goes into society. Billy falls in love with Babe, Sally's pretty young sister, and takes a job under Sam, Sally's ex-sweetheart. Then things happen that cause Sally to go out of society, a fortune-hunter to go to the hospital, and two pairs of sweethearts go to the minister.
