Hundreds of years ago, on the ruins of the great Constantinople, a crusader and the brave knight Baldwin of Flanders saves a Greek monk. In gratitude, the monk passes the savior a sacred relic of the Byzantine temple—Mary’s ring.
Dark forces hunt the artifact, and Baldwin vows to protect it forever—both in life and even after death.
In one of the restaurants in modern St. Petersburg, the fateful meeting brings together the naive and romantic Alia Kortneva and the self-assured career woman Alena Kortneva. At first glance, they seem to have nothing to do with each other, yet the universe keeps pushing the girls together, lifting the veil of the mystery of their origins. Alia and Alena will have to untangle romantic twists, decipher the commandments of their great ancestors, and come face to face with the long-lost relic of King Baldwin.
