The legendary Bela Lugosi as "the Vampire" teams up with Britain's much-loved "Mother Riley" in this hilarious comedy adventure. The Vampire plans to control the world with the help of his robot, which accidentally gets shipped to Mother Riley. Through radar control, he contacts the robot and orders it to come to him, bringing along Mother Riley! But his life is turned upside down when he holds this most meddling of mothers captive. "My Son the Vampire" is the last of the Mother Riley film series (1937-1952), lighthearted, immensely popular British comedies that featured the slapstick antics of Arthur Lucan as an Irish scullery maid who gets herself into all sorts of tough spots.
