Батьки Жені, Маша і Максим, їдуть в Голландію на роботу, і надовго. Маша має провести літо в Кучугурах, в сільському будинку діда Івана і бабусі Валентини. Оскільки педагогічне протистояння триває, в Кучугурах відразу ж з’являються Ковальови під двома більш-менш пристойними приводами: по-перше, вони ще жодного разу не були у сватів в гостях; по-друге, Женю потрібно підготувати до вступу в ліцей. Сільською ідилією наступний місяць буде назвати складно, зате Женя знайде першого справжнього друга, рафіновані Ковальови осягнуть принади сільського побуту, познайомляться з нестерпно колоритним Мітяєм і гідно оцінять душевність і відкритість селян.
На перший дзвінок Жені обидві родини їдуть до Ковальових, де Будько потрапляють в незрозумілу й незатишну, але таку захопливу та чарівну атмосферу великого міста. Але найцікавіше, що в результаті безлічі сільських і міських пригод та перипетій, сварок і примирень, несподіваних альянсів і дивовижних одкровень Будько і Ковальови вперше починають відчувати себе однією великою родиною.

Vlad establishes friendly relations with Deus, an IT specialist from Kharkiv, together they produce explosives and take their first fight.

An 18-year-old girl with the nickname Nika arrives in the battalion. She is attractive, bold and fearless. The guy immediately falls in love with her, she manipulates him and gets a weapon through him. Due to the approach of the enemy's troops, the authorities are attacking the enemy's position. Deus was killed, and the shy Vlad at the crucial moment lined up a Russian tank and became a hero in his mouth.

Nika goes to Dnipro, where she meets a man who pretends to be a true patriot and one who cares about the safety of volunteers, but is actually a Kremlin agent. Nika receives a secret task from him.

Lovers go on a rotation to Kyiv, in the capital they face the quiet city life of people who are indifferent to the war, which is 10 hours drive from the city. Police crimes against protesters during the country's revolution also go unpunished. Impressed by the contrast of life in the war and in the capital, Nika, upon arrival at the military base, persuades Vlad and a couple of young men to carry out a terrorist attack in Kyiv to remind civilians of the events in the East.

He and 2 other volunteers are taking out a large number of weapons from the base. The guys are going to Kyiv, Nika is in charge of the operation. In Kyiv, Vlad understands that the girl is using him and is aware of the scale and consequences of what is planned. At the last moment, he refuses to commit a terrorist attack and decides to return to base. Leaving Kyiv, the guys understand that there is not enough gasoline, there is no money. At the gas station, hoping for understanding, they try to refuel the car, but face the indifference of the employee and unwillingness to help. There is a conflict between one of the guys and the cashier, the guy threatens him with a weapon and shoots him in the arm. The boys begin to flee, the police appear. Vlad stops the car, shows the documents. Looking at the documents of a military volunteer, one of the policemen says that he broke sculls on the Maidan like Vlad.
