The Night Visitor

Max von Sydow plays Salem, an insane Swedish farmer who escapes from an asylum to seek revenge on his sister and her family. He begins by killing those he believes are responsible for his confinement, including his sister Emmie and a girl he was with on the night of the murder. A local police inspector, played by Trevor Howard, resolves to uncover the truth behind Salem's conviction and the murders, while Anton Jenks, played by Per Oscarsson, unwittingly becomes embroiled in the chaos as Salem's revenge unfolds.
