The team re-investigates one of Lt. Stillman's cold cases: the 1983 murder of a Chinese-American teen whose Vietnamese girlfriend had been killed by Chinese gang members only three months earlier.
In the streets of Philadelphia’s Chinatown during 1983, a young Chinese man named Jack asks a girl named Tam out for a date. The woman tells not to kiss her so close to his father’s store. Jack’s cousin Warren tells him he won twenty dollars playing dice. A Chinese gang member bumps into them and shows off a gun. Jack enters the store and watches as his father pays protection money to another gang member. Jack’s brother Ling tells him he shouldn’t bring his girlfriend around or their dad will find out. Jack jokes and says he will end up marrying the girl. Later, Stillman investigates Jack’s murder after he is discovered in an alley.
In the present day, Rush finds a shoebox full of drugs and cash under Eddie’s couch. Rush gets dressed and hurries out to work. At the station, Valens informs Stillman that the mother of Jack, Mrs. Lu, is there to speak to him. The mother says she apologizes for the last time she met with him. She remembers when her husband tore up his card after Stillman asked him for information during Jack’s funeral. Mrs. Lu says her husband recently passed away. She explains Jack wasn’t in a gang, but was dating a girl named Tam Sung who was Vietnamese. She says Tam was shot three months before her son was killed. She explains she hasn’t talked since her husband forbade her.
Stillman tells Rush that Jack was a sixteen year old who was shot in the back and the head. He says the Dragon Boys was the gang who ran the neighborhood. Jeffries says Tam was shot by what was thought a stray bullet during a parade. After they learn that Tam’s father Joe owns the same caliber gun that was used to kill Jack, Miller and Jeffries question him. He says he knew Jack was interested in his daughter at the time. He remembers when Taw was shot during a parade. He cheered her on while she waved a flag. After a bullet hit Tam, Jack and Joe went to her body. As his brother Ling pulled him away, Jack told him he saw that the shooters were gang members with dragon tattoos. Joe says he never spoke to Jack again, even during Tam’s funeral.
Stillman tells Miller and Jeffries a man named Tong controls the Dragon Boys while keeping a clean and helpful public image through an organization called the Chinese Trade Alliance. He says Tong contacts the Dragon Boys through a man called the Dai Lo. Rush and Valens meets with Jack’s brother, Ling at the family store. He tells them his father didn’t want them to talk to the police at the time. He explains if he reports a crime which imprisons a Chinese man, his store might get burned down. He remembers when Jack got in a fight with a Dragon Boy named Danny in the store. Another man named Chen walked in and calmed things down. Ling says Danny was killed a while ago. Valens sees that the store worked with the CTA. Rush asks another worker named Warren if he knew Jack and he says he was his cousin. Rush leaves him a card and asks him to contact her when they get some chrysanthemum tea in stock. Miller tells Valens when Danny went to jail, he was always bailed out by a man named Chen. She explains Chen is now the CEO of the CTA. They figure that Chen was the Dai Lo, the communicator between Tong and the Dragon Boys. Stillman and Rush meet with Chen in Chinatown. He says gang members ruin Chinatown. He explains he runs the CTA which provides his people scholarships. They accuse him of being the Dai Lo, but he tells them to have a nice day. Miller tells Jeffries she found Jack contacted a detective named Ray Bianci and shared his theory that Tam was killed by the Dragon Boys.
Stillman asks Ray about talking to Jack. He says he knows he lied in 1983 when he said he knew nothing about him. Ray explains Jack was looking for revenge. He remembers staking outside a casino and seeing Jack pull a knife on a gang member. He put Jack in his car and told him he is trying to save him. Jack said he was upset since the Dragon Boys killed Tam. Ray tells Stillman he paid Jack to translate tapes containing wire taps of the conversations between members of the Chinese gang. Warren walks in the station and brings Rush some tea. He remembers when he told Jack about his sister Stacy getting kidnapped by the Dragon Boys. Jack grabbed some cash and told Warren to wait up while he saves his sister. Warren explains he learned Jack was killed the next day.
Rush waits while Eddie picks her up driving a Italian sports car. He takes her to the beach to go to the fair and watch the sun rise. Rush thanks him for letting her wear a diamond bracelet she thinks he rented. Eddie says it is hers to keep, but she gives it back. Jeffries and Miller talk to Stacy at the station. She is surprised to learn that Warren told them about her kidnapping incident. She says she was young, was missing for a few hours, but doesn’t remember any specifics. Miller says she remembers things when was five and her friend’s dad had a heart attack. Stacy describes when Jack was brought into the room where she was caged. The Dragon Boys searched Jack and saw he was wearing a tape recorder taped to his stomach. She says she never saw Jack again and some guy took her home. She believes she was held at a restaurant owned by Chen. Rush and Valens bring in Chen and ask him when the last time he saw Jack. He says he made sure the tourists that visited Chinatown were safe. After Rush threatens to shut his businesses down, he explains Jack didn’t understand Chinatown. He remembers taking Jack up to his office after he found Jack with the tape recorder. He told him he is a businessman who works with his father. He explains to the detectives that he was being extorted by a cop during the time.
Miller and Jeffries tell Stillman that Ray’s kids were put through college using funds linked to the CTA. Stillman brings in Ray and accuses him of taking money from Chen. Ray says he made a deal to stop the gunfights in the streets. Stillman tells him that Jack trusted him. Ray remembers when Jack asked him if he knew who killed Tam. After Ray said a rival gang member shot her, Jack shared his belief that Chen was not going to be arrested since he was paying him. Ray admits Jack stole tapes that had Chen’s voice on it. He figures the Chinese gang took the tapes after they killed him. The detectives search the store and find a tape. They bring in Mrs. Lu and ask her to listen to the recordings. She says the tape contains the voice of Chen and her eldest son. After they call in Ling, they play a tape where they hear him request Chen to give him some bodyguards to move some drugs. Ling denies being the person on the tape, but Rush says his mom identified him.
Rush gives him a message from his mom written in Chinese. He reads her message that says she brought shame to his father and his family. Ling remembers when Jack confronted him about working with the Dragon Boys. Ling told Jack that he is going to take over the store and is doing what is best for the family. Jack told him he knows Chen sent the Dragon Boys to shoot up the parade. After Jack threatened to tell their dad about the drug shipment, Ling shot him in the back. Ling, Ray and Chen are arrested. Rush returns to Eddie’s apartment, sees the bracelet Eddie gave to her sitting on a table and takes it.
