Linda needs Danny and Baez's help after a co-worker has difficulties with an angry ex. Erin's former mentor has been giving out unfair sentences following the death of his wife.

Frank, the Mayor, Erin and the DA’s office contend with public outrage after a grand jury doesn’t indict an NYPD officer for the controversial shooting of a teenager that was caught on video. When an officer gets shot in a possible case of retaliation, Danny searches for the shooter.

An NYPD whistle-blower claims there's been abuse of power within the organization, so Frank must investigate whether this is true. Danny and Baez are suspicious of a car accident involving a pedestrian and think it may have been intentional.
