Ben Murphy and Bonnie Bedelia star in the made-for-TV suspenser Heat Wave. Murphy plays a young clerk, and Bedelia portrays his young and pregnant wife. During a record-breaking hot spell, the power in their mountain community goes out, and the water supply is dirty and stagnant. The balance of the film concerns the couple's attempt to escape the heat by descending the surrounding hills. Heat Wave would probably have melted in the ratings had it been scheduled in the summer; thus, it was sagaciously slated for a mid-January debut in 1974.
