One of the infinite dimensions existing in the multiverse. Italy. Next or present future.
The international secret services form a team of masked young women, the "Etère", trained in hand-to-hand combat and capable of traveling in size by means of a "time-lapse", an instrument that is worn on the wrist in the guise of a clock. These women are followed by a psychoanalyst, Dr. Walter Jovanovic, to verify the effects of interdimensional travel on the mind of young women.
