Mystery writer Sian Anderson leaves her boyfriend John for three weeks of intense writing in the isolated Greek town of Monemvassia. Upon her arrival in the ancient, deserted, walled-in fortress, she is met by Elias Appleby, the rotund eccentric landlord who guides her through mysterious underground passageways to the house where she will work. He warns her to stay inside at night because of the killer winds that arrive after dark. Sian goes to work only to be interrupted by the arrival of Phil, Elias' handyman, who brings in the supplies, later as Sian writes, at the house across the yard a murder takes place. Elias is brutally killed by Phil. Later, preparing for bed, she hears something in the back yard, looks through the only shutter less window and sees someone digging. Her writer's curiosity aroused, she goes into the yard and checks out the freshly dug dirt. She finds Elias' body. Out back Phil discovers the messed-up grave, realises that Sian is on to him and starts his sinister cat-and-mouse game. He enters the basement and messes up the generator. The lights in the house go off. Later, seeing Phil leave the cottage, Sian attempts to run for her life. Sian runs horrified through the labyrinth of underground passageways. She arrives at the top-most point of the fortress, a dead end path at the base of the granite cliff. She sees the silhouette of a man in the early morning light. She runs toward him asking for help. The man steps out in the open with an ugly smile on his face. It's Phil. He raises the sickle and closes in for the kill. As he is about to strike, an awesome blast of wind slams into him, rips him off the path, suspends him in mid-air like a child's kite for a moment, then pounds him to his death two hundred yards below. Sian Anderson numbly watches the sunrise as the wind calms. The holy clang of a distant church bell echoes in the quiet morning.
