Shades of Blue

Harlee Santos is a detective at the heart of a tight-knit crew of Brooklyn cops. The crew often steps outside the law to protect their precinct.

Harlee struggles with becoming an FBI informant while Wozniak suspects his crew. Harlee suggests polygraphing the entire crew, a plan that backfires.

Harlee refuses to give Stahl incriminating evidence against Wozniak but hands over a resolved unofficial investigation that Tess and Espada initiated.

Loman's guilt over the death of a suspect becomes a liability for the crew. Wozniak sends Harlee on an errand that reveals he has a silent partner.

Harlee and Tess intercept a heroin shipment from a drug lord who discovers Wozniak's secret and tries to use it as leverage to get his drugs back.
