No overview available for this season.
After Sarah Kim is discovered dead, Jeong Yeo-jin recounts her memories of the elusive woman to Park Mu-gyeong — who suspects something is askew.
Mu-gyeong probes Sarah's past through Woo Hyo-eun and finds that her "Sarah Kim" is nothing like the woman others recall — and Boudoir looks even shadier.
Sarah's buried past surfaces: a down-on-her-luck woman with aspirations for luxury, who'll stop at nothing to reach her goal — no matter the cost.
Mu-gyeong presses Kang Ji-hwon about his link to Sarah, and a tangled history begins to emerge — one that also leads to power broker Hong Seong-shin.
Determined to put Sarah away, Mu-gyeong prepares to go public with the case — only to find that every new glimpse of "Sarah Kim" makes his path less clear.
Mu-gyeong races to lock Sarah away for murder before time runs out — turning to Choi Chae-u for help, even if trusting her may cost more than he expects.
Mu-gyeong tries to shake Sarah by going after what she guards most: Boudoir's name. Pushed to the edge, she drops a new name into the case.
As the clock runs down, Sarah fights to protect everything she's built — and Mu-gyeong follows her ever-shifting story, hoping to finally reach the truth.
