The love of the younger representatives, Liza and Nikita, ended a long-standing feud between two branches of the same family, lasting nearly a century. On the eve of the Revolution, their ancestors, Nadya and Vlas, also loved each other, but they were not destined to be together. Due to the machinations of an impoverished nobleman—the envious Ilya Dunayev, obsessed with power and money—Vlas and Nadya parted as enemies.

Since then, life has brought their descendants together once again, but the truce secretly negotiated by Natalya Peregudova and Viktor Makridin was not enough to restore balance. Now, at Gnezdo—the Peregudov family estate—all the living Peregudovs and Makridins, as well as Ilya Dunayev's hitherto unrecognized great-grandson, Roman Yerofeyev, who, like Ilya, is obsessed with the same passions, are facing off to resolve the conflict.

History repeats itself, but now Liza and Nikita, as well as Natalia Peregudova, Viktor and Albert Makridin, Polina and Lipa, who have been through fire, water and copper pipes, find within themselves the will, patience and wisdom to resolve the conflict and achieve reconciliation.
