When Jake, a mysterious young man, shows up in Chance Harbor, he learns a lot has changed since his last visit. For one, the girl he left behind, Faye has discovered she's a witch and has plans to get even with the handsome guy who broke her heart. To complicate things further, he sets his sights on the alluring Cassie, much to Adam and Faye's dismay.

Cassie and Jake look into her father's side of the family, hoping to discover more about her lineage and why she has powers separate from the Circle. Meanwhile, Adam becomes protective of Cassie when Faye reveals that Jake might be hiding something dangerous from them. At the same time, Adam's equally concerned when Melissa's cousin Holden comes to town and catches Diana's eye. A power shift forms between Charles and Dawn that threatens to destroy their plan.

Cassie enlists the Circle's help when she receives a frightening warning about the witch hunters' return. At the same time, her true feelings for Adam and Jake surface during a birthday party that Ethan decides to throw with the help of Diana. Meanwhile, Faye and Melissa take their inner power to a chilling new level when they try a little of Lee's "Devil's Spirit."

After Faye is attacked by the Witch Hunters, Jake, Melissa and Adam set out to save her. Blackwell tells Cassie and Diana that the only way to stop the Witch Hunters is to use their Balcoin blood to unleash the Crystal Skull. Diana is reluctant, but Cassie convinces her it’s the only way to help their friend, but she’ll need to tap into her dark magic to do it. Meanwhile, Dawn and Charles are faced with a new way to get their power back...but at a very big cost.
