Mitya Neverovsky is a descendant of the famous Lieutenant General Dmitry Neverovsky. However, for his parents, Mitya is a complete headache. He does not show any interest in studying, does not want to become anyone, and the phrase "it will do!" could easily be his motto. Having made his cherished wish at the magic Tree in the Artek camp, Mitya is transported back to 1812. In the past, he meets his great-grandfather many times, the famous Lieutenant General Dmitry Neverovsky, takes part in the Battle of Borodino and makes friends with the young Sasha Pushkin.
Two families live on the same staircase. One fine day, the dads boycott the moms, and the moms confront the dads in response. The reason for this is the accumulated family troubles: computer games of one, iron drill of the second, female fatigue, and so on. The hostages of the situation are children who are forced to live in two opposing camps. In an attempt to reconcile their parents, they only aggravate the situation and find the only way out - to call and ask their grandfather, a general of tank troops, to come. With his arrival, a planned "rescue" operation begins, filled with very comical situations.
