New Year's Evil, movie of 1980 directed by Emmett Alston.
It is a rather boring slasher but with an at least interesting plot.
In Hollywood, during a New Year's party on TV, the presenter/disc jockey receives a call from a guy who calls himself Evil.
Evil explains that every New Year's Eve, which means for the 6 different time zones of the United States, a "mean" girl will be killed - and she will be the last one on the list.
Who is he and why does he want to do this?

It was released on Blu-ray in the U.S.A. for the Shout Factory (English subtitles are also present).
