A man married to a witch has to see her once a year: Halloween. Each year he dreads the day, because he knows she'll find out about what he's been doing the rest of the year. When he's unfaithful, she uses her powers to punish him and his lovers.
One of the benefits he gets is immortality. Yet, is it worth it, even when he only has to spend one day a year with her?
Remember the words and we've all the future before us. As long as I live, you shall live.
