Two of Britain’s top free climbers decide to take on one of Yosemite’s most awesome lumps of granite: the thousand vertical metres of El Capitan – via it’s hardest line – with no experience of big walling whatsoever.

The ensuing agony is captured in this spectacularly shot film, that exudes passion and humour and takes a refreshingly honest look at living 6 days in the vertical world.
