Revolutionary Sisters

While working on the job at a construction site, Lee Cheol Soo gets an unexpected letter from the court, a divorce petition by his wife Oh Maeng Ja.

The three daughters rush to the hospital after hearing their father died; they find him alive but unconscious.

Oh Maeng Ja's death becomes a murder investigation, and the detectives suspect each and every one of the family.

Gwang Sik returns but gets taken in for questioning as the prime suspect in her mother's murder.

A witness in Oh Maeng Ja's death claims she saw a woman at the scene of the crime, and all three sisters get taken in for questioning again.

Cheol Soo moves into Bong Ja's basement, but the suitcase he locked securely already got his daughters' attention.
