After miraculously surviving an attack, Prof. Dr. İnan Kural wakes up having lost the last 12 years of his memory and opens his eyes to a completely different life. He is no longer a doctor, he is a patient. He is divorced from the love of his life, and his family has fallen apart. Perhaps he climbed to the very top as a doctor, but along the way he broke the hearts of his friends and almost everyone around him.

Unable to understand how he became such a cold, almost ruthless man, İnan returns to the hospital to rediscover himself in a world that now feels entirely unfamiliar. Even though he must start again from the very bottom, he is determined to stand back up.

As the painful secrets of the past and the sins that İnan knows he committed, but cannot remember, begin to surface one by one, the greatest support in his new life becomes Elif, a young doctor who used to be his assistant. However, there is one thing İnan does not know: Elif carries a much deeper story about him in her heart.
