Dringo i'r Eitha: Climbing to the Limits(2007)

A portrait of a very talented young Welsh climber, Ioan Doyle, age 16, as he races through the grades to reach E5 in his first summer of rock climbing outdoors. His obsession gives his mother, Catrin, nightmares, but despite his mother's instinctive inability to literally "let him go" while belaying, he climbs his first 8a in Kalymnos, Greece, and then continues on to the big walls of Yosemite with his mentor, "Mills", who has a fear of heights.
