Forty years ago, it took the lead with fierce sound effects, and the shock is still extraordinary today. With the flashback of the insane asylum cricket match, the avant-garde musician lives in a quiet village with his wife, and uninvited guests suddenly visit in one day. The mysterious man (Alumpies) claims to have killed his wife and children in the Australian outback and learned aboriginal witchcraft, which can kill people with cries. With an outstretched arm on the coastal dune, the musician collapsed, the shepherd and the sheep were killed, and the charm captivated the wife and took the place of the man. The paralyzed child, the reclining naked woman and the bishop's head portrait, Bacon's three distorted portraits show the abnormal and morbid state of the three protagonists, and the confrontation between civilization and primitive, rational and absurd, real and illusory, expands in the Dolby stereo, which makes the creepy shudder even more shocking.
