Warning: Spoilers for "Chicago P.D." Season 5 follow.
By the time "Chicago P.D." had reached the final stretch of its fifth season, the overarching plot of the season was also at its boiling point. Namely, the conflict between Sergeant Hank Voight (Jason Beghe) and Lieutenant Denny Woods (Mykelti Williamson), introduced on Season 4, had grown exponentially more intense in the tragic wake of their attempted team-up on episode 14, "Anthem," on which Voight's team attempted to rescue Woods' daughter Brianna (Alexa Adderley) from a hostage situation, only for her to be shot dead.
With Woods now blaming Voight for the failure to keep his daughter alive, in addition to his preexisting grudge over Voight having exposed his past misdeeds on Season 4, the lieutenant's vendetta became more dogged than ever. Unable to hurt Woods directly, he instead went after his old friend, Detective Alvin Olinsky (Elias Koteas) — who got wrongfully arrested for the murder of Kevin Bingham (Joseph Siroka), then stabbed in prison, despite Intelligence's best efforts to get him out.
This is the fraught, nail-biting situation in which the "Chicago P.D." team finds themselves as they arrive at the Season 5 finale, "Homecoming."
