Overview - Murder Diary

Years ago, Kara Hui almost poisoned her son (Vincent Wong) and daughter (Joey Thye) because of her schizophrenia. Experiencing great change, Vincent develops an alter-ego who is physically weak but highly intelligent. His alter-ego works hard and becomes a handwriting expert, helping the agile Vincent carry out his undercover mission. A double bomb case and a case featuring bloody words on a nude corpse prompts Chief Inspector Chris Lai to create a task force to find the perpetrator. The task force includes Vincent, psychiatrist Benjamin Yuen, bomb disposal officer Mandy Wong, and forensic entomologist Venus Wong. The four of them get involved in a love pentagon! The “Father of Criminal Investigation” Philip Keung has recovered from bipolar disorder and is appointed to lead the task force as they investigate various mysterious cases. But he discovers Kara may be involved in the mystery behind his wife's (Alice Chan) disappearance. As the puzzle is revealed piece-by-piece, how will they each face the truth?

Overview - The Defected

CID Inspector Benjamin Yuen was originally a rising star on the police force. While trying to save a colleague, he gets shot in the head and his life changes forever. After miraculously surviving, he works harder on cases than before, earning the nickname "Iron Detective." But he is tormented by the side effects. Chief Superintendent Kara Hui is ambitious and has high hopes to become the first female Commissioner of Police. The person who shot Benjamin turns out to be Kara's undercover agent, Philip Keung. Philip has no limits when it comes to helping Kara investigate cases, yet Kara breaks her promise to him while jockeying for power against fellow Chief Superintendent Benz Hui. Enraged, Philip shoots at her and accidentally injures Benjamin. The shot forced Philip to become a defector, but he feels guilty towards Benjamin, so he secretly helps him solve cases. Benjamin and Philip become pawns in the power struggle. Luckily, they get the help of Ben Wong, Chief Superintendent of the Complaint and Internal Investigations Branch. Ben vows to use power to end the power struggle.
