The two veterans of adventure sagas are back again!

As a result of careless handling of the Time Machine (don't do this at home!), Petka and Vasily Ivanovich move along the space-time continuum and fall down to the flying zeppelin from the piece of ice broken off from Alaska. It is 2050, the temperature is fine, the birds are singing, the sun is shining. Russia is reborn from the ruins and becomes the only supreme power in the world. Everything seems to be fine but for these annoying aliens who lay claims again.

Our mother land is in danger! The aliens have already settled down their troopers in the area of Gadukino cataclysm. As it turns out, Ivan the Terrible has concluded a treaty with the aliens: they help him to take Kazan and receive a great sum of money in 2050 for their assistance. The treaty has been signed on a birch bark fairly and objectively and is kept in the historical museum.

So the heroes will have to go the the past in order to correct this paper. Let's right a wrong! Time gives up, space gives up – our heroes and their mate Anka can deal with everything, even change the past.
