Haven

When the local lighthouse crumbles into the ocean, the residents think it might just be a natural disaster but little do they know— Audrey/Mara and her motley crew caused the implosion. And speaking of Mara… sadly, the last time we saw Audrey she wasn't herself.

Still masquerading as Audrey, Mara moves around town plotting her next move and causing mayhem. She even kills an innocent bystander just so that she can steal her clothes.

Nathan, on the run with Mara, solicits Duke's help. Duke isn't happy about helping Mara but he hopes that Nathan will come to his senses soon and realize that Audrey is gone forever.

True to her word, Mara helps Duke release a Trouble to relieve the pressure in his system, but the Trouble she releases causes him to speak gibberish.

When last we saw Mara she'd just realized that Audrey was still alive inside of her and had vowed to kill her off. Since Dwight, Duke and Nathan don't know any other way to bring Audrey's personality out, they keep talking to Mara as if she is Audrey.

Previously, when Nathan and Duke switched bodies, Nathan was attempting to question Jeffrey Doohan at "The Freddie" (A.K.A. the Murray Q. Frederickson Psychiatric Facility). Since Duke isn't much on police procedure, Jeffrey Doohan escaped the facility and is still at large.

Now that Audrey has somehow been separated from Mara, Duke and Nathan decide to keep Mara on Duke's ship for safe keeping until Dwight gets back in town. They really want to turn Mara over to The Guard but without knowing if Mara and Audrey are physically connected, it's too risky.

With Nathan banished into another dimension, Duke and Audrey are left to strategize about how to get him back.

Since Dr. Charlotte Cross, from the CDC (Centers for Disease Control), just showed up in town looking for him, Dave decides to get in front of the problem by enlisting the aid of Chris Brody, a local marine biologist who has a "charm" Trouble.

The sickness outbreak that's been plaguing Haven has reached epic proportions and all hands are on deck to stop it, including Pete, who usually hides the Troubles from the public. Sadly, it turns out that Pete causes this particular Trouble. Even worse, he can't be talked out of it.

Duke's roiling troubles and a new threat to Audrey leave the pair with no alternative but to turn to potentially dangerous allies for help.

Divided loyalties put the gang at odds; and a terrifying revelation changes everything.

The revelation of Mara's endgame spurs Audrey and Nathan to pursue a plan to stop her once and for all.

Dwight tries to coordinate efforts to suppress the new outbreak of Troubles, while Dave and Vince learn the truth about Dave's visions. Meanwhile, Nathan and Duke try to calm a Troubled girl, and Audrey and Charlotte search for the source of the fog wall.

The no marks killer strikes again, and Vince and Dwight cover up the murder. Meanwhile, a darkness-based Trouble is killing people, and Nathan takes a team to the power plant to restore power before it's too late. In Halifax, Duke meets the daughter of an old friend who is eager to learn if she is Troubled.

Nathan is innocent of Kira's death, but he can't reveal her location without giving away the aether cache. While Charlotte and Dwight go to rescue the woman, Nathan stands trial to buy them the time that they need. Meanwhile, the darkness closes in as Audrey discovers the Troubled person responsible for the deaths.

Audrey is trapped in the Sandman's world and forced him to marry him, and has no memory of her real life. Meanwhile, Duke meets Darkside Seeker Seth in Halifax and discovers that he doesn't remember Haven or the Troubles.

While Charlotte and Audrey try to harvest the hidden aether, they discover that a new Trouble is targeting them along with Nathan and Dwight. Meanwhile, Duke and Seth travel to North Carolina and make contact with the man who can supposedly cast out Troubles.

Things seem too good to be true when Nathan and Audrey stumble across a Trouble that can resurrect the dead. They soon bring back Charlotte, but discover that resurrection comes with a terrible price. Meanwhile, Dave and Vince go hunting for Croatoan.

Nathan and Vince travel back to 1983 to try to find the Troubled person who created the thinny that Croatoan used to kill the Colorado Kid. Meanwhile, mysterious men capture Duke so that he can meet with their employer.
