At the end of the first season, Sheriff Wournos chose to "self-destruct" because he could not bear the torture of supernatural forces. Before he died, he told Nathan to take over the position of sheriff and continue to protect Harbor Town. He also told Audrey that some people did not want her to come back. Audrey admitted to Nathan that Lucy was not her mother, but herself (reincarnation). Nathan revealed that he could feel Audrey's touch. A woman who claimed to be FBI agent Audrey Parker suddenly appeared and asked "Audrey" to explain the whole story. In the second season, Chris Brody (Jason Priestley), the son of the mayor of Harbor Town, will appear on the scene. He is also a person with supernatural powers. At the same time, Duke's wife Evi Ryan (Vinessa Antoine) suddenly returned to the town, and she seemed to have her own plans. In the first episode of the second season, Audrey and Nathan discovered that a supernatural force will spread a deadly plague to Harbor Town. At the same time, Audrey has to face the black-haired "self" - she not only has her name, but also has all her memories!
