Utilities(1983)

One of Bob Hunt's neighbours' electricity is cut off because she cannot pay the bill. She is assisted by contributions, and the bill is paid entirely in pennies, though the clerk is belatedly told that payment is not accepted in such a large quantity of coins. Unfortunately, the electric company fails to reconnect the power due to a communications snafu, and the elderly woman is taken to hospital suffering hypothermia. Hunt sets off on a vendetta of revenge, sabotaging assorted support systems.
