The House of Hate is a 1918 American film serial directed by George B. Seitz, produced when many early film studios in America's first motion picture industry were based in Fort Lee, New Jersey.

Plot

Shortly after Winthrop Waldron, munitions magnate and head of the house of Waldon, arranges for the betrothal of his only heir, his adopted daughter Pearl, to her cousin so that control of his munitions empire will remain in the family, he is mysteriously murdered by a black-cowled killer who has sworn an oath of hate against him and Pearl. With Waldron's death, Pearl becomes owner of America's largest munitions factory - the Waldon War Works. Harry Gresham, a young scientist/engineer, is in love with Pearl, and after the betrothal she finds that she regards him more highly than she does her cousin. Another cousin, Naomi, is in love with Gresham and does her best to block his efforts to win Pearl.
