"Some Questions are Better Left Unanswered"
THE MAID is a Thai film recently released on Netflix on July 9, 2020. In the story, Joy tried to solve the mystery behind the sudden disappearance of her sister, Ploy, by working as a maid in a mansion where her sister used to work prior to her disappearance. The movie is nice though not very scary. It only shows that ones over devotion to her employers and to her profession can be her make or break. The movie is entirely dubbed in Thai language; hence you'll have to be diligent in reading the subtitle all the way while watching.
