After surviving a severe attack, Prof. Dr. İnan Kural, the distinguished chief physician of Umutpark Medical Foundation Hospital, returns to life with no memory of the past 12 years. He finds himself in a world that feels completely unfamiliar. The years he lived are far from even being memories for him, and he struggles to recognize even himself. Surrounded by unfamiliar relationships, incomprehensible bonds, and unanswered questions, he is forced to rebuild his life from scratch.
