During military exercises, the commander of the landing regiment sends three groups of saboteurs to the enemy's rear. Their task is to detect and capture a disguised command post. To complete the task they have not much time - two days. In case of failure of the operation, they will be defeated in the exercises, which is completely unacceptable. They will execute the order in conditions as close as possible to the combat ones. Two groups of saboteurs are defeated and captured.
