Qian Yuying (Gui Lunmei)'s husband Zheng Zihan (Yang Youning) unfortunately passed away after a leg amputation operation. Qian Yuying wanted to get her husband's amputated leg back, but the hospital made things difficult for her and passed the buck to each other, so a whimsical "leg-grabbing plan" began! She pestered the surgeon for help, ran to the basement of the hospital that most people had never seen, and searched for her husband's leg in a bag of specimens. She even asked the office staff to monitor the GPS of the hospital's cooperative vehicles, and the hospital director came to show concern... And this journey full of black humor to find the leg also evoked Qian Yuying and Zheng Zihan's past memories from acquaintance, love to mutual debt. Zheng Zihan fell in love with the beautiful ballroom dancer Qian Yuying at first sight, and became her dance partner under the matchmaking of his friend John (Zhang Shaohuai) from the photo studio. The two fell in love and entered into marriage, and they were a fairy couple that everyone envied. But zheng zihan, determined to make big money for his wife to live a good life, forced their relationship into a desperate situation, eventually became a new way, not expecting that the two hearts were close again when the hospital was faced with separation...
