A young wife is left to take care of her dreadfully ill husband. She decides to end his suffering once and for all so she and her lover can be together with the help of a witch. Which has horrifying consequences.
Definitely Night Gallery at it's very best. The ending, I think, is just superb and almost predictable in a classic horror story fashion that is sure to bring chills down your spine. This is why I love Night Gallery, the masterpiece that is only second best to the Twilight Zone. From the mastermind that is, the great, Rod Serling.
