The Restoration at Grayson Manor (1970)

Irish playboy Boyd Grayson delights in bringing men home to his sprawling family estate for sex, just to spite his legacy-obsessed mother Jacqueline, reminding her she’ll never get the grandchildren she craves. When an accident leaves him incapacitated, Boyd finds himself handless, helpless, and at the mercy of her care. Luckily for Boyd, his mother’s familial wealth has given him the opportunity to be the first person in the history of the world to pilot an experimental technology: mechanical hands controlled entirely by his subconscious. Soon, however, the hands begin to move on their own... even when they’re not attached to Boyd’s body.
