The film has an interesting development. A special band Nine by Nine provided a core of the film taking on the roles of nine grandchildren in a family murder drama. They were set up for a specific time (have since been disbanded) to do some music albums and at least this one movie. In looking for a suitable format the producers patched together some ideas from Hong Kong films. Some scenes are set in Hong Kong
It is supposed to be a Chinese family long established in Thailand. That seemed new, but with English subtitles I came to assume they were speaking in Thai which sounds a little different than Chinese I have heard in other movies. When the scene switched to Hong Kong, the Thai characters spoke in English when speaking with locals.
The first two episodes establish the family. It consists of the grandparents who have established a major hotel and huge bank accounts. Four families all live in high end houses along the same side road. The Grandfather dies and leaves a will that treats his sons much better than the daughter. The daughter Phatson had worked at the hotel for 22 years and was considered excellent. Confronting the brother left in charge he slaps her. Later she approaches him at his home, but is confronted with his bleeding dead body. She flees and is spotted by her grandmother. She becomes the first suspect, but shortly we learn of another suspect, but there are a lot of episodes to go. His will also causes resentment. Each episode provides another twist or wrinkle. All four families are involved with mixed amounts of co-operation and distrust.
I believe viewers will find it as engaging and smooth to watch as your typical Hollywood production.
