Julia is a college student studying psychology who, as a child, was haunted by "night terrors", now those nightmares begin coming back. Her friend Billy, who had similar dreams as a boy, also reports that his terrors have returned. Julia's boyfriend, Paul, is certain they're both just imagining things thanks to too much studying and too little sleep. When Billy turns up dead, Julia is convinced something really is out to get them.
