Two different worlds, different fates, but there is something in common that makes them similar to each other: both appeared as a result of cruel experiments. As a result - lands poisoned by radiation, crippled lives, mutilated societies. But people do not lose hope. In both worlds, they share a common goal: to survive at all costs. Therefore, the day will surely come when, without knowing it, some will come to the aid of others, and the invisible connection between realities will become tangible and durable more than ever.
