A dangerous terrorist nicknamed Azer has escaped from a Norwegian psychiatric hospital. The search for the criminal is entrusted to the German Taleev Special Task Force. The fighters realise that this escape is not accidental. Someone is planning to use Azer to carry out a large-scale terrorist attack. But where and when will it happen? The investigation leads Taleyev's team to a northern city, where the dismantling of a nuclear submarine reactor is in full swing in the harbour. It seems that a deadly action is planned here.
