Bizeza Dout, returning to Earth in 2037 with the help of the Primordials, some mysterious and powerful beings, is tormented by the memories of the five years she spent on the strange planet Mir, a mixture of places and peoples belonging to different periods of human history. Why did the Primordials create Mir? Why did they bring Bizeza back to Earth one day after her initial disappearance?

Bizeza's questions are answered when scientists discover an unnatural anomaly in the core of the sun, which was caused by extraterrestrial intervention two thousand years ago. Now, the plans of the mysterious beings, which were set in motion countless light-years away from the planet, are about to bear fruit with a solar storm that will wipe out all life on Earth, bombarding it with deadly radiation.
