Big Love Series Finale Spoiler Alert!

Big Love‘s swan song is just around the corner — 38 days to be exact — and HBO has released the ultimate appetite whetter: An insanely spoilery preview of the March 20 series finale.

Let’s get the housekeeping notes out of the way first: The hour-long farewell, titled “When Men and Mountains Meet,” was written by co-creators Mark V. Olsen and Will Scheffer and directed by Dan Attias (the dude behind some of the show’s best episodes, including season 3’s epic road-trip eppy).

And now for the official and scoop-packed episode description: “With the specter of jail time looming, Bill charts out contingency plans for the family, while orchestrating a last-minute preemptive referendum on the senate floor. Meanwhile, Barb goes forward with her plan to join a reform-minded church; Margene contemplates taking a hiatus to serve as a volunteer abroad; and Nicki despairs being left alone as her family splinters. Cara Lynn considers a return to her roots; Ben enlists Rhonda to help him win over Heather; Don shares some bad news with Bill about Home Plus. As Easter arrives, the Henricksons receive heartening support from their polygamist constituents, briefly lifting the dark cloud that’s been hovering over the family since Bill’s election. Finally, an unexpected vision leads Bill to a final confrontation with his most deeply-held beliefs.”

Um, yikes! Barb switching churches? Margene leaving the states? Home Plus sold out of lawn mowers? Which plot development made you gasp? Hit the comments!
