The two main characters, Maks and Albert, played by Jerzy Stuhr and Olgierd ?ukasiewicz, respectively, submit themselves to the first human hibernation experiment. Instead of being woken up after a few years, they find themselves awoken in the 21st century, in a post-nuclear world, where all humans have retreated to underground living facilities, and, what's most important, where men had died out as a result of subjection to a specific kind of radiation.
Maks, a born hedonist, isn't at all worried - he sees the opportunity of being a "reproductor" for mankind, but Albert doesn't share his feelings. The plot get's interesting at the point when the main characters are told that women have no interest in the rebirth of men, and that for the good of their society, the two males are to be "naturalised" (undergo a sex-changing operation). At that point the two decide to somehow escape.
