Planet of the Vampires

“This was the day the universe trembled before the demon forces of the killer planet!”

Two spaceships answer a signal from an unexplored planet and crash on its fog-bound surface, and Captain Mark Markary (Barry Sullivan) wakes to find his own crew attacking one another. Mario Bava fills the rock and mist with unseen presences, and the survivors, Sanya (Norma Bengell) among them, can no longer be sure whose hands they are watching. Markary and Sanya hold on to each other, since each is the only face the other has left to trust.
