In the season finale, things come to a head in Harlan when the worlds of Raylan, Boyd and Bo Crowder collide.

The Crowder and the Bennett clans go to war over control of Harlan, a move that leaves dead and dying on both sides.

The race to find Drew Thompson puts both Raylan and Boyd at odds with a dangerous Harlan hill country clan.

Detroit mob leader Nicky Augustine targets Winona in order to convince Raylan to turn over Drew Thompson, while Boyd and Ava devise a ruse to dispose of Delroy's corpse.

As Raylan investigates the Crowe crime family's role in the disappearance of a corrupt Florida Coast Guard officer, Boyd revives a failed drug deal to help keep Ava's murder case from going to trial.

Raylan guides Ava through the process of informing on Boyd and tries to turn Boyd's old ally Dewey Crowe against him as well, all while Boyd works to pull off a daring heist right under Raylan's nose.
