Three boys tormented a poor student during the graduation celebration ten years ago, not knowing the type of retaliation that would follow years later 
Three boys from the class chose to “have some fun” with the reserved, straight-A student at the school prom ten years prior. She rarely spoke to others, was reserved, and was always bashful. People said that her mother was a cleaner and that she had no father. Although the youngster didn’t offend anyone, people like her are frequently singled out for abuse.
The males began to tease her during the celebration. It appeared to be a joke at first, but gradually they gained confidence. While one muttered something hurtful, the other grabbed her hand and forced her to dance. When she failed to respond, the boys, believing they could do whatever they pleased, did something shameful and ruined the life of a helpless girl.
She yelled out and pleaded for assistance, but nobody arrived.
She sobbed when she told her mother, her sole relative, that evening when she got home. However, her mother disbelieved her and expelled her from the home.
The girl vowed that her tormentors would eventually pay for their actions, even if she was alone, poor, and living on the streets in the middle of the night. She started formulating a revenge scheme. They would be cruelly punished ten years later
Ten years went by. The girl was different. She was now employed as a senior investigator for the police. She was calm and self-assured, yet she secretly remembered everything. She recalled that night, she recalled the boys, and she silently tracked their lives for ten years.
She was aware that she required a motive, a suspicion, and an arrest before she could simply toss them in jail.
After a few months, odd occurrences began to occur nearby. The bodies of people who vanished were later discovered. Almost no traces were found.
Pieces of evidence began to turn up at crime scenes “by coincidence” after the detective took on the cases, all of which pointed to the same three boys from her school.
ripped garments, fingerprints, and even security camera footage. It everything appeared to be a coincidence, but the parallels were too great.
The three individuals were suspected by the police one after the other. One was taken into custody, the other ran away and vanished, and the third passed away inexplicably. It appeared that justice had been done at last.
However, nobody was aware that the well-known police investigator who had been abducting and murdering people in order to exact revenge on those who had destroyed her life was the real culprit behind all of those atrocities.
After that, the inquiry started to find discrepancies. Timelines, logs, and cameras all began to point to her.
Her figure was spotted close to a crime scene in one footage. They discovered fabricated reports in the archives.
She made no attempt to defend herself when she was brought in for interrogation. Her eyes were downcast as she sat silently. She didn’t say anything at all.
The silent girl of the past had just completed the task she had vowed to complete ten years prior.
