Mansion of the Doomed

In this gruesome 1976 exploitation horror film, an insane surgeon's desperation to restore his daughter's sight leads him down a dark path of eyeball harvesting and transplantation, resulting in a mansion filled with mutilated victims and a descent into madness. As the transplants fail and the body count rises, Katherine, Leonard's assistant, becomes horrified by her boss's actions, while Nancy's blindness returns, leaving her father to contemplate the true cost of his obsession. The film's graphic gore and themes of nihilism and violence are on full display, making it a notorious example of the "video nasty" era of horror cinema.
