When We Were Knights tells the story of Flanders and long-time climbing partner, Matt Blank, through gorgeous first-person GoPro footage recorded by the pair from their various jumps together. The story unfolds through voiceover, as Blank reads a letter he had written to Flanders, which was to have been delivered in the event of his own death. The ironic conceit makes for an incredibly touching, profound story – not the type of video that GoPro is accustomed to producing.
