The Werewolf's Heart

In 1913 Universal released the first werewolf movie in the history of the cinema. That film, The Werewolf, introduced a half-breed Navajo wolf-witch named Watuma. Subsequently all prints of the film were destroyed in a fire and the movie is now a "Lost Film". There has not even been a reliable synopsis of the film, until now.
Included in this work is the full synopsis of the film from the "Universal Weekly".
After a hundred years, this is the first sequel to that film.
A posse of lawmen pursues a band of outlaws to a haunted mountain where both groups find themselves prey to supernatural evil that hungers for flesh. Their only hope is an ex-monk turned trapper who has a secret past with the Werewolf and the steel nerves of a U.S. Marshal who will stop at nothing to see justice done.
