A year after Becca, Izzy, and Cassie accidentally resurrected the Sanderson sisters, the trio is forced to team up with the Dennison family in their quest to protect Salem from the lingering threat of a powerful witch who was accidentally resurrected by teenagers Poppy, Isabella, and Travis using a candle from Gilbert's magic shop. Poppy, the rebellious young daughter of Max and Allison Dennison and niece of Dani Dennison, doesn't believe her family's story about their encounter with the Sanderson Sisters thirty years ago. However, she is thrust into a world of witchcraft when she and her friends unleash Druscilla The Dreadful, the Elder Witch. The witch, more powerful than any witch in the history of Salem, seeks to cast a dangerous spell called the Shadow Curse. To cast the spell, she must obtain the blood of a witch with the purest heart: Becca. In order to ensure Becca's cooperation, Druscilla kidnaps Poppy, Isabella, and Travis. Becca, Izzy, and Cassie must convince the Dennisons to resurrect the only witches powerful enough to help them defeat the Elder Witch: the Sanderson Sisters. For the first time in thirty years, Max, Allison, and Dani come face-to-face with the Sanderson Sisters, and though reluctant, must put all of their differences aside to save Salem and the rest of the world from the clutches of dark magic.
