Step into the shoes of Dr. Alex Everhart, a quirky and underappreciated cardiothoracic surgeon who discovers he has been mistakenly given the power to inhabit the hearts of his patients during their surgeries. Each heart reveals not just the physical condition, but the emotional turmoil, regrets, and unfulfilled dreams of its owner. As Dr. Everhart traverses through these different lives, he must solve emotional puzzles, mend fractured relationships, and save lives—all while juggling the chaos of the hospital, a scheming rival doctor, and an unexpected crush on the hospital’s heart nurse. Will he learn the true meaning of empathy and connection, or will he lose his own heart in the process?
