Two brothers, who are both hunters and live with their mother, go to the mountains to set traps for deer. Suddenly, a demon grabs the younger brother. The older brother shoots an arrow, severing the demon's arm, which they plan to take home. But they make a grisly discovery on the journey home.
Unfortunately the movie The Demon is not yet available on HBO Max.
