An old friend is worth two new ones - a truth tested by time. But you can't say that about love at all!

Talented St. Petersburg journalist Olga finally decided seven years later to formalize a relationship with her child's father, Sergei. Why such a wonder? Yes, because all the same seven years ago, her ex-boyfriend Denis literally ran away from the crown. And, as you know, once baked in milk, you will then blow on the water. Six-year-old daughter Masha is very happy with this decision of her parents. It would seem that everything is fine and everyone is satisfied. But before the wedding, Olga is sent on a business trip to Moscow, where she accidentally meets Denis. He tries to get his ex-girlfriend back. Olga resists with all her might.

Meanwhile, Sergei is actively preparing for the wedding, and Denis does not give up his attempts to return his beloved. And finally, he succeeds. He deceitfully lures Olga to himself, and she can not withstand the attack - the bastion falls: the daughter, the groom - do not care. Ahead - a new life, a new job, old love! All so, and not so. It does not work. And Denis's tender love - as if it never existed! Olga finds herself with nothing! But here the daughter Masha comes into play. She persuades Sergei to put on a suit and together they go to Moscow, break into the party and the "knight" calls Denis "to a duel." However, Olga convinces the groom that Denis "does not even deserve punishment."
