Quiet life spins out of control when Han Joo Won, an extremely competent investigator who seems to have everything (performed by Yeo Jin Goo), becomes his companion — and when an occurrence resembles 20 years ago from a serial killer crime shakes up their town.

Explaining why he selected the drama for his next venture, Yeo Jin Goo commented, "I was attracted to the distinctive feeling that separates 'Monster' from other suspense style dramas, realistic roles, and the plot emotions.
