S1 E1: Knowing that the ferocious mobsters kidnapped IT mogul YANG TAOGUO, quick-witted police officer WONG TAI-MUI immediately calls headquarters for backup. While the police are opening fire on the kidnappers, TAI-MUI risks her own life to give pursuit, during which a canopy collapses, hitting and injuring a passer-by and his dog. On impulse, TAI-MUI expresses radical criticism in a media interview, and she ends up being relocated to a station in Cheung Chau shortly after she gets promoted to Sergeant. Going to the hospital to visit the injured passer-by, BOWIE, TAI-MUI promises to look after his dog. Later on, she bumps into BOWIE again when she brings the dog back to her ancestral house in Cheung Chau, and she even recommends him to go sketching at CHEUNG PO-TSAI Cave. Having returned to the dry seafood store run by her elder sister, TAI-MUI notices her elder sister, TAI-NUI, is working so hard alone there; whereas her husband FU MA is a penny pincher, so TAI-MUI cannot help thinking that it's not worth her sister's while doing everything for this cheapskate brother-in-law. TAI-MUI then goes to the police station to report for duty, and all of her co-workers turn out to be her childhood acquaintances. Among them, Senior Inspector LEUNG KIM-FUNG, an astronomy enthusiast, gravely tells TAI-MUI that many unexplained, paranormal phenomena have happened in Cheung Chau while welcoming her back. Going to the CHEUNG PO-TSAI Cave to make some sketches, BOWIE has an accident, during which something strange happens. With TAI-MUI getting informed by the dispatcher about the collapse of the CHEUNG PO-TSAI Cave, it's discovered that BOWIE is trapped inside the cave, and he cannot move as both his legs are crushed by the stones. TAI-MUI goes to his rescue, and upon her departure, she finds an old silver coin. She then turns on her flashlight to look at it in detail, fascinatingly, a shadow bearing a striking resemblance to CHEUNG PO-TSAI out of the blue flashes by behind her...
