Shadowless

Mor, a young Myanmar engineer, is promoted to Deputy Head of Production. At the same time, he brings his younger sister, Zin, to work at the same factory under the supervision of Nui, the Quality Control Manager. Mor's promotion and Zin’s arrival raise suspicions among some of the factory workers. This includes Wit, the Head of Production Line A, who has constantly been at loggerheads with Mor throughout their time working together.
A tense atmosphere engulfs the factory and intensifies dramatically on the very first night of these organizational changes, culminating in a mysterious murder that claims the life of Sor, Mor's close friend, whose life is lost to the shadows.
To uncover the truth, Lieutenant Narong leads his investigative team to take on the case and find out... who is the killer?
