In December 2012, a 23-year-old female college student in Delhi, India, was on a wrong bus when she and her boyfriend were returning home from a movie.
Six men, including the driver, raped the girl before two were thrown off the bus.
After 13 days, the girl died in hospital.
This is the "Delhi Black Bus Case" that shocked the world.

The film is based on this infamous case.
Devi (Shri Dai) is a university teacher who teaches biology.
The husband is an executive of a company, has two daughters, and the family of four lives a prosperous life.
It's just that the eldest daughter, Alia (Saja Ali), is not biological and has always been hostile to her.
Aria is a student of Devi, and she only calls mrs. on weekdays, never called her mother.
Devi didn't care about this either, and still loved her wholeheartedly.
One day, Aria and her friends make an appointment to go to a dance party together, and the boys in the same class invite her to play together, but she does not agree.
The boy had harassed Aria at school before, and she had always refused outright.
Aria decided to go home with her drunken friend and told Devi, who had called, to be home in about forty minutes.
The phone was interrupted and Aaliyah was hijacked into a car by a male classmate and several others, unable to call for help.
Devi waited for two hours and still did not see Aaliyah come home, and began to become anxious.
She called everywhere, went to the prom to look for it, and even went to the police station to report the crime.
The policeman, on the other hand, ignored the question, saying that the young man might have gone to play somewhere else.
The next day, a passerby found a scarred, dying Aria in the canal.
After rescuing Aria from danger, she spoke out of the four men who had committed the violence.
After a round of trials, the court acquitted the men.
The reason was that Aria had drunk that night, and all her testimony was rejected.
The family was angry and helpless, but they could only prepare to appeal.
If it is still a normal adaptation here, the subsequent revenge process is slightly magical.
The stepmother finds a private investigator who has had a relationship and asks him to help find information about the four men.
Then the stepmother embarked on a journey of revenge.
The first was the security guard at the prom, and his stepmother found someone to castrate him and left him at his doorstep.
When he woke up, he found himself castrated and fell to his death in a panic.
The second generation of the rich who is keen on fitness hopes to eat a variety of protein powders and muscle building powders.
The stepmother cut countless apples, removed the seeds, and extracted the toxins.
Then sneak into the home of Fu Er Dai and put it into his nutrition.
This was followed by measures against the third student and the fourth social.
Will the revenge go well, and will the police link the two cases?
Personally, I think the adaptation of this film simplifies the vicious case in India.
In reality, the girl was brutally tortured, sent to the hospital to lose her intestines, and finally died of her serious injuries.
The girl in this play was also tortured for a night, but the description of her injury is too superficial.
The hospital has been discharged from the hospital for a period of time, and as one criminal after another has been killed, the psychological trauma has also improved.
If life had been as ideal as in the movies, India might not have erupted in mass protest marches.
In reality, after public protests, except for one juvenile with a light sentence, several other criminals were sentenced to death.
The young girl lost her life forever.
Maybe it's just that the reality is too dark, and the people get some comfort through the film.
