In early 1934, the Soviet exploration steamship “Chelyuskin” is ice-bound in Arctic waters, where the crew has finally managed to escape onto the ice. In a Prague neighborhood, five children hear the news on their self-made radio and decide to rescue the crew. As they embark on their journey, they soon encounter problems that eventually force them to return home.

Based on the children’s book by the successful East German author Alex Wedding, this film includes documentary footage from the original exploration that traveled the Northern Maritime Route from Murmansk to Vladivostok.
