Count Fernando, called Didino, a shy and sexually repressed man, lives under the oedipal authority of countess Mafalda, his bloodsucking and over-controlling mother, until their family hires a new young maid that changes his life.
Unfortunately the movie To My Dear Mother on Her Birthday is not yet available on HBO Max.
