The Earth is in danger! Our place will soon be taken by Souls - aliens deprived of a fleshy shell, displacing the mind from human bodies and replacing it with their own mind. Most of humanity has already died. The few survivors go into hiding in a pathetic attempt to delay the inevitable...Now the Soul is trying to take over the body of young Melanie. However, the unexpected happens: Melanie and her Soul are forced to coexist in one body. The guest was supposed to track down and hand over the rebel earthlings with whom Melanie is connected, but she helps her carrier. Will humanity soon find itself in slavery to immortal masters? This will happen if the girl standing between the world of conquerors and the world of people does not do the impossible!
