Alison Parker, a beautiful but neurotic fashion model with a history of suicide attempts, moves into a historic Brooklyn brownstone that has been divided into apartments. The top floor apartment is occupied by a reclusive blind priest, Father Halliran, who spends all of his time sitting at his open window. Soon after moving in, Alison begins having strange physical problems, including fainting spells and insomnia, and hears strange noises from the apartment above hers. Alison meets her odd new neighbors, including the eccentric, elderly Charles Chazen, and attends a bizarre birthday party for Chazen's cat. When she complains to the rental agent Miss Logan about the noisy and irritating neighbors, she is told that the building is occupied only by Halliran and her. Miss Logan proves this by showing Alison the various empty apartments, including ones Alison had recently visited and seen occupied. Alison's lawyer boyfriend Michael initially believes she is suffering paranoid delusions, but secretly contacts his corrupt detective friend Brenner to look into the situation.
