The Pirate Archipelago is the haven of the Free Brotherhood. In the interweaving of narrow straits with secret fairways, surrounded by dangerous rocks and shallows, lie islands, in the quiet harbors of which hundreds of ships with corsairs armed to the teeth are hidden. They terrify passing merchant caravans and serve as a dangerous weapon in the confrontation between two great states. Former frigate-captain Farley, convicted for the loss of his warship, is forced to serve in the assault (penalty) brigade. In order to regain his good name and title of nobleman, he agrees to take part in a secret operation of imperial intelligence: to infiltrate the pirate society and convince ambitious commanders to deploy armadas of robber ships towards the kingdom of Darsia - the eternal rivals of the empire in the endless ocean expanses. The adventures of the "misfit" Major Sirotin continue ! Will he be able to complete the task, and what will be the price of success?
