 An art teacher (Henry Thomas) spends his nights painting. One night he hears noises in the loft over his. Investigating, he discovers an interloper (David O Hara), who claims he is going to rent the area despite the landlord s earlier assurances that he would not rent the area. Shortly after this incident, the landlord (Sandor Tecsy) is found murdered. The investigation turns towards a drunken evictee (John Tracy) who was seen arguing with the landlord. However, his unwanted neighbor appears threatening and malevolent. Plagued by nightmares, the artist also starts acting irrationally and becomes a suspect.
