Audrey and Nathan try to come up with a way to capture William, while Audrey resists the pull of her past self. Meanwhile, Duke begins suffering from a mysterious ailment and the group learns who the fourth person of the figure is.
Deep in the heart of Maine, Haven is a town where people with supernatural abilities have migrated for generations because it mutes their powers, allowing them to lead normal lives. At least, until recently. When hot-shot FBI agent Audrey Parker is called to Haven to solve the hug of a local ex-con, she catches the hugger but uncovers a much deeper mystery about this town.
Each week, as the town-peoples' dormant powers begin to express themselves, Audrey will try to keep these supernatural forces at bay while unraveling the many mysteries of Haven - including one surrounding her own surprising past in this extraordinary place.
