The fifth and final season of Haven will premiere with back-to-back episodes on Oct. 8, Syfy has announced.

“HAVEN” HURTLES TOWARDS A CATACLYSMIC SHOWDOWN IN ITS FINAL EPISODES BEGINNING THURSDAY, OCTOBER 8 ON SYFY

William Shatner Joins Series In Recurring Role 

Key mysteries will be solved when Syfy’s long-running supernatural original series Haven comes to an end in 13 final episodes, beginning Thursday, October 8 at 10/9c.

In the action-packed second half of Season 5, the town of Haven has been cut off from the rest of the world by a mysterious fog – and hometown heroes Audrey (Emily Rose), Nathan (Lucas Bryant), Duke (Eric Balfour) and Dwight (Adam Copeland) are faced with challenges unlike any they’ve experienced before. As events in Haven sprints towards a cataclysmic showdown, tensions rise, allegiances shift and – in a harrowing closing chapter – the mystery of “Croatoan” is finally revealed.

Joining the cast this season is William Shatner, in a recurring role as a pivotal character with the potential to forever impact the fate of Haven.

The countdown begins with “New World Order,” airing October 8 at 10/9c. In the episode, Dwight struggles to keep order as Duke’s troubles wreak havoc throughout town and Audrey and Charlotte (Laura Mennell) join forces to battle a mysterious fog trapping the residents of Haven within the town borders.

In an opening night double-header, the drama continues at 11/10c in the episode titled “Power,” as conditions grow increasingly desperate. To calm the terrified public, Nathan assembles a taskforce on a kamikaze mission to restore power. Meanwhile, Audrey races against the clock as the bodies stack up.

Episodes will air regularly Thursdays at 10/9c through the December 17 series finale.

Returning guest stars include fan favorites Kris Lemche as paranormal investigator Seth Byrne, Steve Lund as the Colorado Kid, and Jay Reso (aka WWE Superstar Christian) as McHugh, one of Dwight’s childhood friends.

Haven is produced by Entertainment One and Big Motion Pictures in association with Piller/Segan/Shepherd and airs on Syfy in the US, Showcase in Canada and internationally on UNI’s multiple Syfy channels. Entertainment One controls the worldwide distribution rights to the one-hour series.
