A mountaineering play adapted from Karl Heinsell's novel: Italian Karel and British Winper compete for the first summit of Matterhorn. Wenper's first group of people reached the mountaintop, but his companions hurriedly left on their way back. It is said that Wenper had to save himself by cutting the rope. Since the loser Karel climbed Mount Matterhorn again, it was the rope that tore, not the one that cut, that Wenper proved his innocence. Trenk later remade this movie as' The Challenge 'in 1938.
