The sixth and final season of FX gunslinger drama 'Justified' will more than heat things up, as Raylan and Boyd might well burn down the entirety of Harlan County with their legendary rivalry. Ava Crowder might just let it happen too, judging by the latest fiery teaser trailer for the 2015 swan song of 'Justified.'

Still lacking any actual footage, but nonetheless symbolically intriguing, our latest look at 'Justified ' season 6 sees Raylan Givens (Timothy Olyphant) attempting to navigate the flaming Crowder residence, coming face to face with Boyd (Walton Goggins) in the same predicament. And who should get the better of both men, locking the doors to the exit but Ava Crowder (Joelle Carter), perhaps an ominous portent of things to come?

Elsewhere, we know of 'Justified' season 6 that 'Parks and Recreation' star Sam Elliott will take the role of legendary Kentucky gangster Markham, who returns from exile to win back his empire and the lost love of his life, Katherine Hale (Mary Steenburgen). Timothy Olyphant's former 'Deadwood' co-star Garret Dillahunt will play former soldier turned private contractor Walker, while 'LOST' star Jeff Fahey will appear in multiple episodes as hill country mining veteran Zachariah Randolph.

When last we heard of 'Justified''s final run, producer Graham Yost teased the possibility of a time jump that would bring Art Mullen (Nick Searcy) out of his hospital predicament for one last case, while Marshals Tim (Jacob Pitts) and Rachel (Danielle Brooks) would also receive a more prominent spotlight. Boyd will return to his role as the season's central antagonist, though plenty of other criminal agents new and old will make their presences felt as well.
