After Danny discovers his nephew has been working undercover within a gunrunning organisation for the ATF and his cover may be blown, the Reagan family bands together to prevent him from being killed in the line of duty like his father.

Frank battles with City Council Speaker Regina Thomas over protests against police brutality; Jamie and his nephew, Joe Hill, try to locate a missing Danny and Baez; Eddie helps an abrasive woman find her father's body.

Eddie and her partner, Officer Rachel Witten, are heralded for their bravery for stopping an active shooter, until a civilian comes forward to accuse them of faking the incident as part of a government conspiracy.

After Danny witnesses a drive-by shooting, he butts heads with the detective assigned to the case; a childhood friend of Jamie's is convinced that she has single-handedly solved a cold case murder.

As Jamie and Eddie's wedding day grows closer, Erin begins to doubt Eddie's honesty. Danny and Baez look into the complex love life of a young man who was killed.

Eddie clashes with her new boss, while Danny gets Baez caught up in a case involving a grieving, yet suspicious couple.
