|The first season introduces orphan Audrey Parker to the town of Haven. Brought there by the influence of her superior, Agent Howard, Audrey initially comes to investigate the death of an escaped convict. However, she becomes intrigued and stays in Haven when she discovers that a woman who may be her mother was involved in a local murder 25 years ago. Audrey requests a leave of absence to stay in the town and help the local police, and eventually resigns when Howard threatens to reassign her.|
From there, Audrey encounters different "Troubled" individuals, and discovers that she has a gift for calming the often out-of-control abilities of the Troubled. Much of the season is devoted to her exploration of her background, and ends in several major revelations for Audrey, the sum of which she may not be who she believes herself to be.
Aiding her in her investigations are local police officer Nathan Wournos, who is one of the Troubled, with an inactive sense of touch. Although initially skeptically of the strange phenomena, Nathan ultimately explores his truth. The second main story arc of the season is Nathan learning that his biological father is not the man who raised him, Chief Garland Wournos. Nathan becomes attracted to Audrey and vice versa, although right now neither one of them seem interested in pursuing a romantic relationship given the issues between them and the troubles that plague the town of Haven.
The third main character is Duke Crocker, a smuggler and petty crook who can get anything for anyone. He's also attracted to Audrey, and seems disappointed when she chooses to confide her secrets in Nathan instead of him. Duke has his own problems when a Troubled individual prophesies his death at the hands of a man with a tattoo forearm. Duke is unaware that someone close to him bears the tattoo.
The thread running through the season is that of a series of cracks that are spreading throughout the town, representing the fracturing that lies beneath the surface of this seemingly innocent little Maine town. It's ultimately revealed that Chief Wournos is one of the Troubled, and his inner strife is manifesting. He kills himself rather than risk his beloved town, but he may yet live.
Haven is a town of secrets, and many of them are unresolved at the end of the season. There is a mysterious group of supporters, led by Reverend Ed Driscoll, who want to maintain control of the town. They view the Troubled as a threat to that control, but also use some Troubled individuals like Max Hansen to do their dirty work.
There are also a group of individuals, perhaps the same ones, who all have maze tattoos on their forearms. Their goals and motives are unknown, but they murdered the Colorado Kid 25 years ago, and will apparently murder Duke as well if the prophecy bears out.
Overall, the theme of the season is setting up the coming conflict, and peeling back the first layer of Haven's mysteries... only to reveal deeper secrets below.
