C. Church. His widowed brother, Edgar, a guardian of morals is dying and dividing his fortune into six - to his four daughters, their sister, Madeline and to him. But he doesn't want to share and hires him to seduce his sister and nieces, in order to have an excuse to be disinherited. With the help of his producer friends, George and Archie he seduces all the women.
