With the proliferation of private climbing gyms and the sport's inclusion in the Olympic Games, climbing, long a counter-cultural movement, is undergoing a profound transformation and facing a major paradox. On the one hand, private gyms are enjoying increasing popularity, while on the other, natural climbing sites are under serious threat. What vertical legacy will we leave to future generations? Is outdoor climbing destined to disappear? What will the future hold for climbing? Led by Cédric Lachat, a multi-award-winning Swiss climber, the film provides an international overview of this counter-culture, which has recently become a social phenomenon.
