While Jolan and his companions finally learn from Manthor what their grand destiny will be, Thorgal is still on the trail of the men who kidnapped his other son, Aniel. Along with the jolly mercenary Petrov, he sails down a frozen river aboard a blade ship—a trade vessel specially equipped to break the ice. The journey will be fraught with danger of all kinds—storms, raiders, spies, wild animals...—as well as a group of shipwrecked Vikings looking for a mysterious chest.
