Policewoman Yiu Chi-yue is a natural born Highly Sensitive Person. She brings chocolate, salty lemon water and a brain with an “on-off switch” with her whenever she investigates cases. Her senses are heightened when she drinks salty lemon water that arouses her keen awareness of clues at the crime scene. Through touching the dead body, gathering evidence and her senses, she empathizes with the victim and reconstructs the sequence of events. Since Chi-yue met restaurant boss Wong Mik-kei, the duo are no longer “spectators”. Perpetrators at large are killed one after another. Chi-yue covertly challenges some serial killer on several occasions, and their true identity is gradually uncovered. Chi-yue realizes the two of them have conflicting standpoints even though they are like-minded, causing her to face the conundrum of making life choices. In the meantime, Mik-hei astonishingly makes some decision for her.
Delivery truck driver, Uncle Chuen, works hard every day to put food on the table. His only son, Chong, is only interested in photography. Uncle Chuen doesn’t like how Chong idles his days away doing nothing, and this is a frequent flashpoint between the two. One time during an argument, Uncle Chuen slapped Chong on the face, and Chong ran out of the house, but didn’t forsee that Chong would be hit unexpectedly by a car. Uncle Chuen and his wife rushed to the hospital, but there was no way to save him. The director of organ donation at the hospital found out that Chong had registered as an organ donor before he died. Although Uncle Chuen still could not accept his son’s death, he pushed through the pain to fulfil his son’s dying wish, to leave a gift to those still alive.
