Intro. Dmitri Volkov is a mysterious man who leads a double life. To the world, he is just a cold and reserved telecommunications engineer. In fact, he is a highly trained Russian spy involved in dangerous missions and secrets that cannot come to light. In the midst of this secret life, he meets us and, for the first time, feels something real. He falls in love and decides to marry us, trying to live a normal life with us. What we don't know is that, on an old mission, Dmitri ended up forming another family in another country, a part of his life that was never ended. Jealous, intense and emotionally complicated, he becomes overprotective and lives in constant conflict between duty and love. As he tries to protect us from invisible dangers, he struggles daily with the fear that the truth will come to light. Torn between two lives, he no longer knows where the mission ends... and where love begins.
