A group of four teenagers all begin to have the same strange dreams about Freddy and then one of them is gruesomely murdered in her sleep. The survivors soon realise that if Freddy kills them in their sleep, then they will die in real life too. Thus begins an ordeal of wakefulness as they try to find some way to stop Freddy.
