When Sammy and On are selected to represent the Hong Kong Police Force, little did they know what they are in for. The Force needed to project an image of young, attractive, intelligent, go-getting and energetic cops, akin the fresh rays of sunshine, hence the name "Sunshine Cops". Sammy and On are put through a hectic schedule of promotional activities and with the media on their backs, they no longer have their privacy, which gets them more and more frustrated. They began to question their reasons for staying in the Force, for they are now merely 'models' not cops. (Universe)
