We're mere days away from the two-hour series finale of "Fringe" (hold us!) and Fox has released a tantalizing new promo for the cult show's final installments.

Narrated by our beloved "mad scientist," Walter Bishop (John Noble), the trailer promises an epic, cinematic climax to one of television's most consistently daring, gripping and heartfelt dramas. Will Walter sacrifice himself to save the world? Will Peter (Joshua Jackson) and Olivia (Anna Torv) be reunited with daughter Etta (Georgina Haig)? Will the Observers finally be defeated? We only have a few days to wait -- and stock up on tissues -- before all is revealed.

Noble recently described the show's ending as "one of the great finales of all time," while producer J.J. Abrams said, "If it's not satisfying, I don't know what satisfying is."

Check out the finale trailer and the newly released episode stills from "Liberty" and "An Enemy of Fate" below.
