The team re-opens the 1989 murder of a young Russian opera star, eighteen year old Nadia Koslov who defected to the United States. She and her family sought asylum at the police station where Nick Vera was stationed when he joined the force.
Nadia Koslov was visiting the United States with her family from the Soviet Union. The family escaped guards to defect to the US after performing at a concert in Philadelphia. The family entered a police station to ask for help. The father knew little English and spoke to the police clerk in Russian. Vera worked in the precinct during that time and knew a little Russian. Vera set up a meeting with the State Department. He gave Nadia's younger brother, Dmitri, a card and told him to give him a call anytime he needs help. He saw that Nadia was carrying a bag covered with patches and gave her a Philadelphia Police patch.
Nadia died four months after she arrived in the U.S. Her body was found at the bottom of the stairs in a subway station.
In present day, Vera was called to meet with a young man. He and Rush meet the young man and find that it is Dmitri, who claims that he found the man who stole his dead sister's bag. Vera recognizes the patch on the bag and brings the man's cousin, Michael "Beamer" Hyacinth, in for questioning.
The team looks into Nadia's case and find that she was 17 years old when she died. In 1989, she was found dead with blunt force trauma to the head, bruises on her body, and laying next to a cassette player boombox without a tape.
The team questions Michael in the interrogation room. Michael says that he was in the subway when he heard Nadia dying at the base of the stairs. As he approached her, Michael heard someone running up the stairs with shoes that made a clickety clack noise. Michael approached and heard her say the word, 'Zolotoi.' He grabbed her bag then left her to die.
Later, Vera and Rush meet with Nadia's dad Leo and his son. The detectives ask if they know what the word 'Zolotoi' means. Dmitri says that it means 'gold'. They say that before Nadia died, she was attending the Regis School of Performing Arts. Leo says that someone there might be Nadia's killer.
Detectives Miller and Jeffries travel to the school to try to learn more about Nadia. They are met with the principal named Elliot Glick. The detectives find that there is a line of female students waiting to meet with Elliot. He brings the detectives into his office and tells them that he was the head of the drama department at the time. He says that he didn't interact with Nadia very much because she was in the vocal department. He says that he was with his wife at the time. Elliot says that he has been divorced twice already and has remarried. He says that Nadia was in the advanced vocal class taught by Phoebe Curtis.
Rush goes to meet with Phoebe who says that she taught a small class that included Nadia. She says that Nadia's final project was to tape a solo street performance. Phoebe says that Nadia died before completing the project. Phoebe recalls Nadia in her class struggling to find her voice. Instead of singing what she felt, Nadia sang in a very technical manner. Nadia got upset and went into her bag to grab her inhaler for her asthma. Phoebe recalls that when she reached into her bag, she poked herself on the thorns of a black rose that was planted by Chelsea Cutler, a student that was booted out of the class to make room for Nadia. After Nadia died, Chelsea was let back into the class.
Miller performs a test on Nadia's bag and finds that they have traces of oil of wintergreen. Miller explains if taken by an asthmatic, oil of wintergreen can cause a heart attack. She says that oil of wintergreen also causes purple blotches to appear on the person, making it look like they have been beaten. The team figures that Nadia was poisoned and fell down the stairs.
Rush and Valens meet with Chelsea in the interrogation room. She admits that she was angry at Nadia for taking her spot, but didn't kill her. She says that Nadia became Cyrus's, one of her classmates, girlfriend. Chelsea says that she saw Cyrus at a gay bar crawl a couple years ago.
Valens and Miller question Cyrus in the interrogation room. Cyrus says that before she died, he dreamed of writing songs for her. He says that he thought he was bisexual at the time. He remembers walking with Nadia in school and finding Nikki crying and doing drugs in the dressing room. He remembers that Nadia offered to help Nikki, but Nikki got angry and broke a mirror. Later, Nikki was expelled for doing drugs.
Later, Valens and Rush meet with Nikki at the backstage of a show. Nikki tells them that her peers told her that she was too short for ballet and should give it up. She says that she punished herself for her inadequacies. Nikki explains that she was already kicked out of school by the time Nadia and Cyrus caught her doing drugs. She recalls one time when Elliot brought the class to his apartment. Elliot was dropping oil of wintergreen on the heads of the students as they lay down on the ground in a circle with their feet pointed out. Nikki recalls Nadia leaving before getting a drop on her head. She says that Elliot gave the oil dropper to Phoebe to give to the rest of the students, then talked to Nadia. Nikki watched as Elliot offered his support to Nadia.
Elliot is called to the station for questioning. He explains that he was using the oil for meditative purposes. He says that the tried to protect Nadia. He recalls being at school when Nadia approached him. Nadia told Elliot that her father was very strict and only wanted her to practice, even on the day of her mother's funeral. Elliot recalls having Nadia sing 'True Colors' and having her father, Leo, walk in and become angry at her for practicing non-opera music. When she stormed out of the room after an argument, Leo chased after her.
Later, Rush receives a response to an email that she sent to a Russian professor, inquiring about the word, 'Zolotoi'. She is told that 'Zolotoi' is a name given to Nadia's father. Leo was an acclaimed vocal trainer and was honored with the name, translated to English, meaning golden one.
Vera meets with Leo in his store. He brings a bottle of vodka and has a few drinks as they talk. Vera tells Leo that he knows that he is 'Zolotoi' and that Nadia spoke his name in her dying breath. Leo says that he didn't kill her daughter. He says that he became proud of her after seeing her perform. He recalls watching Nadia sing 'Free Fallin'' on a street corner. When Leo showed up, Nadia saw him and began singing 'Va, pensiero', an Italian song about freedom and homesickness. He says that Nadia recorded the performance- her final project.
Later, the team finds that Phoebe lived two blocks away from the subway where Nadia died. Rush and Valens question Phoebe in the interrogation room. They tell her that they investigated her old apartment, and found that oil of wintergreen was all over the place, and had seeped through the linoleum floors. They find that Phoebe had a relationship with Elliot and became jealous that he was paying too much attention to Nadia. She recalls that she was going to poison and kill herself with oil of wintergreen, but then Nadia arrived at her apartment. Nadia played Phoebe the tape that she recorded on the street. Phoebe admits that she thought that if she got rid of Nadia, she could get back with Elliot. She gave Nadia the poisoned tea that she was going to drink herself. After Nadia started to choke from the poison, Phoebe brought her to the subway where she tumbled down the stairs. The team then arrests Phoebe for murder.
