2005, North Caucasus. The special operational combat group "Sandal", having completed the task of destroying illegal armed groups, returns to its home base. However, the helicopter was shot down, leaving only a few people alive. Meanwhile, changes in the political situation force the Center to refuse to acknowledge the presence of Sandal: the old commander quits and dies under mysterious circumstances, and the new one carries out the order and destroys all documents, especially since the group is considered deceased. The surviving fighters, with “legends” instead of biographies, find themselves outside the law. The federal forces consider them militants, the militants – on the contrary. They are forced to act according to the situation and in the Caucasus mountains they are trying to find an ancient assassin dagger of great value... The only person who refuses to forget about the group is Lieutenant Colonel Nizhegorodtsev, who covered Sandal during the fighting. Will he be able to return the forgotten heroes to their place in life, and will they be able to find an ancient artifact?
