After years of practicing medicine abroad, skilled surgeon Tang Jia Yu returns to China to lead the Heart Center at Ankang Hospital. Tasked with forming a critical illness team and developing artificial hearts, she faces resistance from colleagues who doubt her. But through a series of challenging surgeries, she slowly earns their respect.

Jia Yu forms a close working relationship with anesthesiologist Ye Yi Ming, but just as their bond begins to deepen, the return of her ex-husband and a failed artificial heart surgery throw her personal and professional life into turmoil. When the project is shut down, Jia Yu steps away from the hospital and travels to remote areas in need of heart care.

There, through hands-on work and life-saving surgeries, she rediscovers her passion for medicine—and the strength to start again.
