Zabil jsem Einsteina, pánové...

It is the beginning of the third millennium and the situation of the human race is critical. Secret experiments with the G bomb has caused women to grow beards and completely lose their ability to bear children. The only hope is an expedition which Professor Moore wants to make in his time machine, planning to go to Prague of 1911 and kill Professor Einstein, whose calculations eventually resulted in the production of the G bomb. Moore is accompanied by mathematician Frank Pech and pretty historian Gwen Williams. Their plan is based on historical records, according to which Einstein almost died in the house of the banker Wertheim, standing under a heavy chandelier which fell on the exact spot he had stood on just a while ago. The task of the group of three is only to help the tragedy a little - to thwart the scientist's rescue. The time machine lands in Prague but, gradually, everything goes wrong. Frank makes friends with an ingenious little arithmetician and great rascal named František, his future father. But the boy dies instead of Einstein and Frank - who thus could not have been born - disappears in an instant. The expedition has failed. Moore asks for a new attempt. This time, Gwen decides to use her women's charms against Einstein, convincing him to abandon physics and take up a career playing the violin. But when the expedition returns to the future, everything has changed. Moore finds out to his horror that he had remained the only one real man. Chemistry, which came to rule the world in the new history instead of physics, caused a "female" mutation to men, preventing them from having any descendants. Moore can do naught else but engender new generations and invent the "salutary" nuclear bomb. (oficjalny tekst dystrybutora)
