The Girl Who Sees Smells

After her parents are murdered, a young woman awakens from a coma with total amnesia, and crosses paths with a cop who suffered a loss of his own.

Choi Mu-gak agrees to help Oh Cho-rim with her comedy skit in exchange for assistance on a case that could earn him a spot in the Violent Crimes Unit.

Cho-rim leads Mu-gak to a body in the river and is later followed. Mu-gak reveals to Cho-rim how he lost his sense of pain, taste and smell.

A new barcoded body is found, but Lt. Yeom Mi suspects it's a copycat killer's work. An accidental injury brings Cho-rim to Dr. Cheon Baek-gyeong.

When a strangled chef falls off a roof, Kwon Jae-hui becomes a suspect, but a scent leads Cho-rim elsewhere. Mu-gak learns why Baek-gyeong went to Jeju.

A confession letter is written and stored. Ju Ma-ri's journals are discovered. Mu-gak figures out what the barcodes on the victims' bodies signify.

The Barcode Killer places the next body so it will be found and covers his tracks. Cho-rim's friend Ma Ae-ri is accused of stealing from her employer.

Mu-gak is rushed to the hospital, where the police set a trap for his attacker. The Barcode Killer decodes his last victim's cryptic final message.
