The Doomsday ship is approaching; humanity seems doomed to extinction. Everywhere in the world, news of the approaching end of the world has given rise to chaos, looting and the collapse of the legal system. Against the backdrop of the collapse of the foundations of civilization, Jack and Mia engage in a race with time itself in an attempt to find the answer to the main question: why an alien race periodically erases life from the “face” of the Earth ? Maybe the key to stopping this cycle of extinctions is hidden in the Salzburg chromosome? To solve the mystery, they will have to plunge into the dangerous world of an extraterrestrial civilization and come face to face with the creatures that gave birth to us.
