A Witness Out of the Blue (2019) (Blu Ray) (English Subtitled) (Hong Kong Version)

A man is found dead inside an apartment with a strange noise, "Help! Help!" next to the body. Detective Larry Lam (Louis Cheung) arrives at the scene with Detective Charmaine (Cherry Ngan) and his commanding officer Yip Sau Ching (Philip Keung). Yip Sau Ching is convinced the deceased, Homer Tsui (Deep Ng) is killed by his partner in crime, Sean Wong (Louis Koo) when they had a fight over how to divvy up the loot from an armed robbery 3 months ago. But Larry soon finds out the case is more complicated than they imagine and not only Sean but there are also other suspects. Larry’s only hope in cracking the case lies in the not-so-human sole witness left at the scene of the crime – a parrot which can talk.
