“You Can't Spell H-ell Without It.”

New killings begin in the city, each victim a pregnant woman, each murder matching the crimes of Shin Hyun (Cho Seung-woo), a convicted killer who is still locked up. Detective Kim Mi-yun (Yum Jung-ah) and her partner Kang Tae-hyun (Ji Jin-hee) start to suspect he is steering the copycat from his cell. Lee Jong-hyeok keeps Mi-yun at the center, working the case while it presses harder on her.
