The film follows Robbie Phillips, Calum Cunningham and Alan Carne as they attempt to open a new climb, ground up, on a 700m Big Wall called Tsaranoro Atsimo in Madagascar.

The walls of Tsaranoro are as wild and bold as the country, the rock beautifully carved as if by providential hand, and the story... that of a real adventure of friends taking the risks that come hand in hand with pushing boundaries. Once the free climbing begins disaster strikes, Alan takes a bad fall shattering his lower right leg, an epic ordeal unfolds to get Alan from the remote big wall to safety. From here the mood changes, Robbie and Calum are left with some big questions and bigger fears as they must decide whether to continue with their push or give in to their emotions as they learn the hardest way possible what it takes to open a Big Wall on one of the sheerest vertical faces in Africa.
