Cadets from naval academies set sail on the training ship Nadezhda for the shores of Australia. They were about to cross several seas for the first time, sail across the ocean, and take part in an international sailing regatta. For most of the young men, this was their first time at sea, and this voyage would determine who among them would become a true sailor and who would have to leave the fleet.
