Two champion climbers, young Martin and experienced Roger, compete to be the first to conquer a daunting snow-covered peak.
[1][2] The film is based on the history of the supposed first conquest of the summit of Cerro Torre in 1959, by the Italian climber Cesare Maestri and his partner, the Austrian Toni Egger, who died during the descent.
Maestri's claim was later challenged as he failed to give substantial proofs on reaching the summit.
