Lieutenant Captains Pyotr Orlov and Ivan Muravyov have been serving on the Slavyanka submarine for a long time. The next trip to the sea is a planned combat exercise. But no one assumes that a catastrophe will happen this time — the waves from the training explosions will disturb the "sleeping" naval mine since the Second World War.
