Jessie and Axel are both friends and mineworkers at the small town of Valentine Bluffs. They are in love with the same girl Sarah who used to be with Jessie since he left the town. Now that he is back again, there is going to be a conflict between him and Axel. They will face also the frightening crimes of the serial killer Harry Warden who returns at the city after twenty years continuing the bloodbath. The reason of the killings is that he was left dying in the mine from his irresponsible bosses who have gone to a party so he hates Valentines day and kills everyone who celebrates on it. It is a cult film and a surprising success as also a wonderful addition to the slasher genre of the 80s. A must seen for horror fans!
