Ballerina

Jang Ok-ju learns that her best friend Min-hee committed suicide and that Min-hee's last wish was for Ok-ju to avenge her. She resolves to uncover Choi Pro's crimes and to stop him from harming others. This realization sets her mission in motion and frames the entire sequence of events to come.

Ok-ju searches for Choi through his internet profile and identifies his address. She begins shadowing him from a distance, watching as he sells drugs to various customers. This surveillance marks the first concrete steps in building a case against him.

The morning after the stakeout, Ok-ju breaks into Choi's home and plants listening devices. She uncovers a drawer full of USB drives, including one labeled ballerina that contains a video of Choi assaulting Min-hee. The evidence confirms Min-hee's abuse and devastates Ok-ju emotionally.

Ok-ju watches the Min-hee video with growing horror and realizes the full extent of Choi's crimes. The footage personalizes the pain Min-hee endured and hardens Ok-ju's resolve for revenge. She understands that stopping Choi Pro is now a personal mission.

A few days later Ok-ju learns that Choi will be at the Heaven nightclub and goes there to confront him. Choi approaches her with a flirtatious line and she buys him a drink before they leave together. They head to the hotel where Min-hee was filmed, setting up the confrontation.

At the hotel, Choi attempts to drug Ok-ju, but she pretends to ingest it. When he begins filming the assault, she fights back and tries to stab him. The struggle draws the hotel staff's attention, and a high school student kept as a sex slave helps them escape, fleeing in Choi's Lamborghini.

Back at the gang's base, the leader expresses disappointment that Choi drugged women and made explicit pornography, but clarifies he never authorized such abuses. He orders Choi to bring Ok-ju in within three days, heightening the stakes. The warning pushes Choi to intensify the pursuit.

Choi visits the drug pharmacist to source more sleeping agents and discuss tracking Ok-ju down. The two hatch a plan to locate her, and Choi promises the pharmacist 100 million won for help. The alliance tightens as the hunt intensifies.

Ok-ju reaches out to an old friend to procure weapons, preparing for the inevitable confrontation. She shows resourcefulness and urgency, knowing the clock is ticking toward a dangerous showdown. This step marks her transition from investigation to active retaliation.

Choi and the pharmacist track down the stolen Lamborghini using a corrupt police contact. The pursuit intensifies as they close in on Ok-ju's location. The chase directly connects their resources and demonstrates the reach of Choi's operation.

Ok-ju returns from a convenience store to find the high school student missing and is suddenly ambushed by Choi and the pharmacist. She fights back and escapes through the window, narrowly avoiding capture. The attack demonstrates the escalating danger and Ok-ju's determination to stay free.

Choi lies to the gang leader that he has killed Ok-ju and buried her in the mountains, prompting the leader to order the high school student killed for witnessing. Instead, Choi and the pharmacist torture the student to learn Ok-ju's whereabouts. The tension between loyalty and survival intensifies the looming confrontation.

Ok-ju finally locates the base of operations at the hotel and proceeds to eliminate its members who refuse to reveal Choi's whereabouts. With the base cleared, she gathers crucial information about Choi's location. The raid marks a turning point in the pursuit.

A brutal sequence unfolds: the high school student fires, then Ok-ju shoots Choi repeatedly. They burn him on the beach to end his reign of terror. Afterwards, Ok-ju retrieves the USB drives and a notebook of customers from Choi's house and drives off into the sunset, reclaiming control of her life.
