The Creeping Flesh

Professor Emmanuel Hildern (Peter Cushing) returns from Papua New Guinea with his paleontological discovery, a humanoid skeleton that grows flesh when exposed to water, unleashing a malevolent entity on his family and friends. As his daughter Penelope (Lorna Heilbron) becomes increasingly unstable after being injected with a serum meant to protect her, the lines between reality and madness blur, and Hildern's sinister half-brother James (Christopher Lee) seeks to exploit the situation for personal gain.
