Shock

Shock (Italian: Schock) is a 1977 Italian supernatural horror film directed by Mario Bava and starring Daria Nicolodi, John Steiner, and David Colin, Jr. Its plot focuses on a woman who moves into the home she shared with her deceased former husband, where she finds herself tormented by supernatural occurrences. It was Bava's last theatrical feature before he died of a heart attack in 1980. In the United States, the film was released under the title Beyond the Door II as an unofficial sequel to Beyond the Door (1974) and second entry into the Beyond the Door trilogy. Plot Dora Baldini, her seven-year-old son Marco, and her new husband Bruno Baldini move into Dora's former home, where she lived during her first marriage to a man named Carlo. While Dora was pregnant with Marco, Carlo, an abusive heroin addict, was thought to have committed suicide at sea after his boat was found adrift. The incident resulted in Dora having a nervous breakdown and being placed in psychiatric care. With Bruno away as a commercial airline pilot, Dora is left all alone with Marco and only her shattered memory of the events of her former husband's death, caused by extensive electroshock treatment she received while institutionalized. Marco experiences various strange occurrences in the home and is inexplicably drawn to the home's basement. Dora notices bizarre changes in Marco's personality and is disturbed to find he has shredded her underwear. Unnerved by Marco's behavior and other frightening occurrences, Dora pleads with Bruno that they move out of the house, but he ignores her. While Bruno is on a flight, Dora finds a bundle of roses with a note addressed to her from Carlo. Suspecting Marco wrote it as a twisted joke, she confronts him and slaps him in the face when he denies writing it. Dora brings Marco to her psychologist friend, Aldo Spidini, for examination. Aldo suggests that Dora's trauma from her marriage to Carlo may be triggering her to project feelings of spite or anger on Marco, though she confesses that she feels that Marco is being possessed by his deceased father.
