K2, the second highest mountain in the world, but reputedly the most difficult, has marked decisively the history and success of the alpinistic-television team of the Spanish TVE «At the limit of the Impossible». The climbers recall the various attempts to scale the mountain from the time of the first expedition on the west face in 1983. Another attempt was made in 1987, along the difficult Cesen route on the south pillar. In 1994, another attempt was made from the Chinese north side.
