Summer Horror Day (1987)

A teenager stumbles upon a mysterious book from which he reads the written words out loud. As it turns out, playing with black magic spells is not the most sensible idea, because soon a bloodthirsty zombie appears, and the carnage begins. However, the curious young man reads another spell from the book in which he then surrenders his soul to the devil. Now he becomes the target of the zombie hunt, and all its victims, who rise up as the next living dead!
