Freshly graduated doctor Mi Ka was at a jewellery store to purchase a gift for her parents when a jewel heist by armed robbers occurred. A special SWAT team was deployed to take control of the situation and this was how Mi Ka met Special Forces Captain Xing Ke Lei when he helped diffuse an explosive situation. However, because Xing Ke Lei was in full combat uniform and had his face masked, she did not know what he looked like. A few years later, when finalising her qualifications to be a full medical surgeon, Mi Ka decides to participate in a joint emergency rescue training exercise between her hospital & the police SWAT team and she unknowingly meets Captain Xing Ke Lei again. A relationship between them begins and eventually develops as they grow to learn more about each other and as they encounter various military and medical situations in future.
