Boyd's plan to keep Ava from being tried threatens to unravel while an unexpected reunion with Loretta McCready pits Raylan against two hit men working for a ruthless Memphis drug lord.

Overseeing an asset forfeiture leads Raylan to discover a crime boss' hidden treasure, while Boyd continues his efforts to try to clear Ava's name. Dewey's cousins arrive from Florida to take over Audrey's.

While working to undermine the murder charges against Ava, Boyd reaches out for new partners. Art steps up his investigation of the Tonin crime family.

As Art's frustration with Raylan boils over, the Crowe family battles both the U.S. Marshals and the Crowders to stay in Harlan. Boyd enlists unlikely allies to ensure Ava's safety in prison and regain control of the local drug trade.
