There was never a thread? Incredible documentary. It's not all about the ending either...the buildup is very interesting and engaging. In addition to being a natural thriller, it's a very quality character study with cool insights into rock climbing craft & culture. Inspiring AF. Bonkers camera shots.

And about the ending...even though you know he makes it, you will still feel all of the tension and nerves from the sheer awesomeness of the task and the stakes. Trust me.
