Vital Signs

After being reassigned to a new station along with his superior, Rock Sir, paramedic Wong Wai is assigned to ride with Jerry Ma. At first, Wai is worried that his work performance review would be affected because he doesn't agree with Jerry's way of working. But after some time, Jerry influences Wai to remember once again that the aim of paramedic work is to save every victim. Meanwhile, Jerry, a single father, is hesitating over the future of his daughter, Bonnie. He can't bear to see her leave, but he finally decides to send Bonnie to Canada for schooling. Before she leaves, she tells Jerry that she's worried about being forgotten when she's in Canada, just like her late mother was forgotten. Jerry tries to explain himself, but it's hard to digest such long-gestating grief. At the same time, a serious traffic accident occurs on Tuen Mun highway. Jerry immediately rushes to the scene for the rescue effort. When Wai notices that Rock Sir cares more about taking over command than doing.
