Her squad of detectives at the NYPD is her family, but when their questionable practices attract the attention of the FBI, Harlee is recruited to work undercover for the FBI's anti-corruption task force must choose between ratting out her team or losing her daughter.

Harlee grapples with the guilt of betraying her crew while Wozniak searches for the informant.

Harlee (Jennifer Lopez) refuses to give Stahl (Warren Kole) incriminating evidence against Wozniak (Ray Liotta) but hands over a fully resolved unofficial investigation that Tess (Drea de Matteo) and Espada (Vincent Laresca) initiated when they moved a body by Tess' house found to be murdered with a 3D printed gun. Wozniak confronts Harlee who executes a dangerous bluff.

As Loman struggles to find his place in the crew, Wozniak sends Harlee on an errand that reveals new details about the job and unwittingly helps Stahl's investigation.

Wozniak's confrontation with a local drug dealer threatens to expose his deepest secret.

Wozniak's (Ray Liotta) suspicions land on Saperstein (guest star Santino Fontana), forcing Harlee (Jennifer Lopez) to convince Stahl (Warren Kole) to arrest Saperstein in order to keep him safe. Harlee visits her abusive ex, Miguel (guest star Antonio Jaramillo), who tasks her with tracking down the man who committed the murder for which he is imprisoned.

After Saperstein's (guest star Santino Fontana) death, Harlee (Jennifer Lopez) realizes there are no lines Wozniak (Ray Liotta) won't cross and decides to help Stahl's (Warren Kole) investigation. The crew retaliates against a pair of abusive cops after they harass Harlee's daughter Cristina (Sarah Jeffery) and her boyfriend. Wozniak makes Loman (Dayo Okeniyi) feel like a part of the unit.

Harlee's collaboration with Stahl uncovers Wozniak's secret as the crew grapples with Saperstein's death.

Harlee (Jennifer Lopez) and Wozniak (Ray Liotta) secure more details on the big score and meet Donnie's (guest star Michael Esper) silent partner, who reveals himself to be a DEA agent. They learn the big score is an armored truck heist. Wozniak takes interest in a fellow marine veteran who is suspected of murder under dubious circumstances.

The armored truck heist is interrupted when a convluence of events forces the crew to improvise a new plan.

Harlee (Jennifer Lopez) and Wozniak (Ray Liotta) must face the consequences of the disappearance of the heist's money. Out of options, Harlee approaches the FBI and promises to find the money and deliver Wozniak and his partners if Stahl (Warren Kole) keeps her in play.
