In the icy expanse of the Giant Mountains during the final days of the German occupation, a band of young heroes embarks on a daring mission to save a French pilot who has crashed. Their efforts mirror the concept of the classic ‘telephone game’—the pilot is discreetly transferred from one mountain village to another, akin to a clandestine message passed around in a schoolyard. However, the stakes are perilously high. The children face lethal soldiers from the occupying forces, must outsmart traitors and informants, and endure the unforgiving winter conditions in the mountains.
