A box set containing all seven of Wes Craven's 'A Nightmare on Elm Street' films.

In the opener, American teenager Nancy Thompson (Heather Langenkamp) begins to suffer from nightmares, only to discover that many of her friends are having similarly disturbed nights' sleep.

Their dreams are haunted by the hideously scarred former child murderer Freddy Krueger (Robert Englund) who, it soon transpires, has the power to kill them in their sleep.

Freddy is out to exact his revenge on the children of those who burned him alive in retribution for his crimes, and the only way to avoid his reprisals is to avoid sleep - but Nancy knows that she can't stay awake for ever.

The sequel 'Freddy's Revenge' is set five years after the original.

The Walsh family have now moved into the house formerly owned by the Thompsons, and it is not long before teenage son Jesse (Mark Patton) is having bad dreams.

He and girlfriend Lisa attempt to work out what is happening to him, but before long Jesse becomes convinced that Freddy has taken over his body in order to continue his murderous rampage.

The second sequel, 'Dream Warriors', features the return of Nancy from the first film, now a psychiatric doctor.

She teams up with Dr Neil Goldman (Craig Wasson) when a group of teenagers at his hospital begin to suffer a shared nightmare, and soon realises that Freddy has returned to continue wreaking his revenge on the descendants of those who killed him.

By the fourth film, 'The Dream Master', Freddy has killed off all the children of those who originally burnt him to death.

Now he's starting to kill their teenage friends. Luckily, Alice Johnson (Lisa Wilcox), one of the endangered kids, has the special ability to bring others into her dreams.

She is the Dream Master, and therefore the only one who can stop the razor-fingered prankster from wreaking more of his murderous havoc.

In 'The Dream Child', Alice is expecting a baby. Unfortunately for her, the meddlesome Freddy finds out about this and begins to control the foetus's dreams, hoping that the birth will be his means of returning to the land of the living.

So the Dream Master sets to work, taking the battle to Krueger one final time.

In 'Freddy's Dead - The Final Nightmare', having wiped out all the children in his home town, dreamstalking psychokiller Freddy decides it is time to head for pastures new.

Luckily for him, he happens across a home for troubled teens and is soon indulging his unspeakable appetites once again.

This was originally intended to be the final instalment in the 'Nightmare on Elm Street' series, but director Wes Craven was unable to resist bringing Freddy back one more time in his 1994 'Wes Craven's New Nightmare', a coda to the series in which Craven and his producer play themselves, persuading the now grown-up Heather Langenkamp (of the first film) to return to Elm Street one more time.

She and Robert Englund are lured back to play their characters again, but this time they cannot walk away from them when they leave the film set at the end of the day...
