Revenge

Maturos divorces her husband and leaves him all the money to get the sole custody of Peung, their only daughter.

She moves to a shady rental as it is cheap but the drug gang in the neighborhood suspects that she is a police informant.

Someone from the drug gang hides a drug stuffed doll in Peung's laundry basket. Maturos turns it in to the police and unknowingly provokes the gang.

On a rainy night, the mother and daughter are violently raped.

The police squad try to catch the gang right away but still too late for Peung who is too shocked to be able to cope with the tragedy.

The suspects are brought to the court but the justice may not be served due to weak evidence.

Yuki is empathetic and encourages Maturos to get her own justice. She was also a victim who did not justice from her case.

To avenge the criminals, Yuki teaches Maturos how to disguise and how to fight.

Maturos is so in rage that she cannot control herself. She starts to hunt the four criminals right away.

Kriengkrai becomes Maturos' first target and it is very hard for her to finish the job.

An old woman stalks Big at his home in a province. He thinks the lady is harmless and let her get closer, until it is too late.

Maturos continues to disguise and changes her personality. Each time, she is farther away from her old self.

Yuki gives Maturos the Japanese assassin's sword. It becomes her weapon of choice. Maturos then moves on to Man as her next target.

The remaining gang start to fear for their lives. Lt. Patorn suspects that Maturos has something to do with the recent murders.

The remaining gang members become more careful. So Maturos has to find a new way to get closer to them.

Maturos disguises herself as a bar girl named Rita whom Lt. Patorn thinks has something to hide. He questions her but cannot find anything.

Dr. Nattha knows the truth about the killer and tries to tell Lt. Patorn while Maturos changes her personality again to move on to the next target.

Jau, one of the gang members, is in jail for only a night and is released. Maturos seeks this opportunity to get to him as soon as he's released.

Maturos' good conscience starts to come back. She wants to stop the whole thing but her revengeful self still wants to go on.

The remaining gang find out about Maturos and want to take a revenge. The police squad try their best to protect her.

The only way out is for Maturos to cooperate with the police so they can catch the last two criminals. Maturos stops the hunt because of Lt. Patorn.

Maturos offers herself as a bait but things do not go as planned. Peung's condition worsens and Maturos cannot control her vengeful self.

The remaining gang use Peung as a bait to lure Maturos in. They all go back to the place where it started. Only this time, Maturos is not a victim.

Maturos's case sparks a controversial social debate about the justice in rape cases, justice system, and vigilante.
