Tarantula

A woman's bloody revenge against a corrupt nation's highest power begins.

Lim Nayoung is a housewife enjoying the sweet life of a newlywed. But one day, her husband returns as a cold corpse, and Nayoung, who feels that her husband, a homicide detective, was murdered, decides to avenge her husband... In fact, the seemingly ordinary housewife was actually a top killer called "Tarantula," a North Korean secret agent dedicated to terrorist operations such as assassination and kidnapping, before she defected from North Korea.
