Dora Baldini (Daria Nicolodi), her husband Bruno Baldini (John Steiner) and her son Marco (David Colin Jr.) move to a huge house that belongs to her. Dora lived in this house with Marco and her former husband, who was drug addicted and committed suicide. The house is empty since them and Bruno, who is a pilot, has decided to move to the place claiming it is close to the airport. Soon Marco is possessed by the ghost of his father and Dora is haunted by the house. She tells to Bruno that they need to leave the house and she is afraid of her son, but he believes Dora relapsed since she had a breakdown when he husband died. Why the vengeful spirit is seeking revenge?
"Schock" is a scary and creepy story of possession and haunted house. The direction of Mario Bava is capable to make a great low-budget film with a simple storyline. Daria Nicolodi has a convincing performance in the role of a traumatized woman that is haunted by the ghost of her former husband and discovers the motive in the end. My vote is eight.
