The plane of ace Vyacheslav Suvorov was shot down behind German lines. He woke up in the hospital. But not in captivity among the Germans, but among family and friends, in our world. Exactly two years have passed since his disappearance, but to Vyacheslav they seemed like an eternity. The thought cannot leave him that he can return to 1943 and bring great benefit to the Fatherland. Having compared all the facts of his time travel, Vyacheslav finds a time portal at the bottom of the lake. Now relatives and friends go with him, taking the main thing - strategically important information and modern weapons. And now seven people from the future break through the German rear to the front.
