THE SUMMIT: The story of the deadliest day on the world's most dangerous mountain

The film, directed by Nick Ryan, attempts to piece together what happend on a single day in 2008, when 11 climbers perished on the second-highest mountain in the world.

The incident became a major news story that summer, although the details of what happened on that day - and why so many people lost their lives - are still murky.

The movie relies on interviews from survivors and uses footage from the actual climb as well as reenactments filmed in the Alps.

We've compiled a shortened version of the story, told using screenshots from the trailer, but recommend checking out the full documentary.
