One day, they meet a Lady in Black who hires them to form a professional gang, of which she would be the leader, indicating the victims and locations through notes and phone calls. But one night, one of the girls is arrested at a nightclub by a decoy, a young woman used by the police to infiltrate suspicious environments. The gang is then dismantled, and the girls go to prison to answer for their crimes.
