Damian Volkov is one of the most feared Russian mafia bosses in Moscow. Cold, ruthless, and impossible to approach, there is only one thing he treasures above all else: a silver ring left to him by his late mother. It is the last memory he has of her. When the ring suddenly goes missing, Damian loses control. He sends dozens of men across the city to search for it, threatening anyone who fails to find it. Meanwhile, Roya Rahimi, a young Iranian woman working at a small pastry shop in Moscow, finds the ring lying on a rainy street. Having no idea who it belongs to, she keeps it safe, hoping to return it to its owner. A few days later, Damian's men track her down. Expecting a thief, Damian confronts her personally. Instead, he finds an honest girl who protected the ring without asking for anything in return. The moment he looks into her eyes, something changes. For the first time in his life, Damian falls in love. What begins as fascination quickly turns into obsession. He finds reasons to visit the pastry shop, secretly watches over her safety, and becomes unable to stay away from her. His feelings grow into a dangerous, possessive devotion. Damian's father, Viktor Volkov, notices the change immediately. Having never seen his son care about anyone before, he becomes determined to help him win Roya's heart, even using the power and influence of the Volkov family to make it happen. But before Damian can confess his feelings, Roya suddenly returns to Iran for several months. Desperate, Damian searches everywhere for her. His men investigate airports, old records, and every lead they can find. Yet she seems to have vanished. Just when Damian begins to think he has lost her forever, fate brings her back to Moscow. The moment he learns she has returned to Russia, Damian decides that this time he will not let her disappear from his life again.
