The Evil Dead (1981)

Ashley "Ash" Williams (Bruce Campbell), his girlfriend and three pals hike into the woods to a cabin for a fun night away. There they find an old book, the Necronomicon, whose text reawakens the dead when it's read aloud. The friends inadvertently release a flood of evil and must fight for their lives or become one of the evil dead. Ash watches his friends become possessed, and must make a difficult decision before daybreak to save his own life in this, the first of Sam Raimi's trilogy.
