The letter that arrived on the FSB website aroused genuine interest among the security officers. It reported that North Korea was preparing a secret operation to remove American atomic bombs that sank forty years ago from the Sea of Japan. North Korea has been threatening the world with nuclear weapons for a long time, and it seems that these threats are of a very specific nature. The underwater adventure of the Koreans should be stopped. A counter-operation is being developed within the FSB, for which Captain Bondar is appointed responsible. When Bondar gets down to business, there is no doubt that the task will be completed. Whistle everyone up!
