Instead of the inevitable drama, Oksana suggests that Seva try... an open marriage. Seva reluctantly agrees, because he himself has been living by double standards for a long time, he has a mistress, his youngest son's teacher. After all, it's a win-win for him. Spouses step into the uncharted territory of an open marriage — hello, freedom!
