On August 2008, twenty-four climbers from several international expeditions converged on High Camp of K2, the last stop before the summit of the most dangerous mountain on earth. Forty-eight hours later, eleven had been killed or had vanished, making it the worst K2 climbing disaster in history.

At the heart of The Summit lies a mystery about one extraordinary man, Ger McDonnell. By all accounts, he was faced with a heart-breaking dilemma – at the very limit of his mortal resources, he encountered a disastrous scene and a moral dilemma: three climbers tangled up in ropes and running out of time.

In the death zone, above 8,000 metres, the body is literally dying with each passing second. Morality is skewed 180 degrees from the rest of life. When a climber falls or wanders off the trail, the unwritten code of the mountain is to leave them for dead. Had Ger McDonnell stuck to the climbers' code, he might still be alive.

If all this sounds familiar then you were probably watching BBC4 last Monday evening, when The Summit was screened as part of the Storyville documentary strand, though curiously under the more sensationalist title of 'The Killer Summit'. Scary, huh? If you missed it then we can assure you that while it's not quite as nail-chewing as Touching the Void, it's still a compelling work and absolutely worth seeing.

The firat feature-lenth film by director Nick Ryan, The Summit will be released on UK DVD on 7th April 2014 by Metrodome Distribution. As is so often the way with Metrodome press releases, we do not yet have a price or any details of extra features or even the cover art. The release date is still some way off, however, so we'll cut them some slack. This time.
