In the era of spiritual awakening, not everyone can become a messenger of light.
Policewoman Liu Shuang has the special ability to control reflected light beams, but this power requires mirrors to exert its true power. When bizarre cases happen one after another, with broken lenses always left around the dead, she begins to suspect that someone is deliberately challenging her abilities.
As the investigation deepens, a mysterious force called the "Mirror Organization" surfaces. Their leader "Mirror Master" seems to know Liu Shuang's past very well, but Jiang Ying, his former partner in justice, is now on the opposite side of the light.
In this battle between light and shadow, Liu Shuang must learn to truly control his own power. Because she is about to discover that the most terrifying enemy may be hiding on the other side of the mirror.
Can the light of justice break through the darkness in the mirror?
