It's present-day in Salem, Massachusetts, and Becca (WHITNEY PEAK) is turning sixteen. While she plans to celebrate with her friend Izzy (BELISSA ESCOBEDO), those two have had a falling out with their other friend, Cassie (LILIA BUCKINGHAM), whose dad, Mayor Traske (TONY HALE), is running for reelection.

Their day, however, is about to change when Becca and Izzy visit the local magic shop run by Gilbert (SAM RICHARDSON) who teaches tourists all but the legend of the town's infamous Sanderson sisters, believed to be witches back in the mid-1600s. Due to the effects of a magic candle, those adult siblings -- Winifred (BETTE MIDLER), Sarah (SARAH JESSICA PARKER), and Mary (KATHY NAJIMY) -- return to their former town with revenge in mind, mainly focused on Mayor Traske whose ancestor was the local preacher who did the sisters wrong back in the day.

With Becca and Izzy trying to warn Cassie about the danger facing her dad -- and hoping to mend their broken friendship -- Gilbert brings back to life a zombie, Billy Butcherson (DOUG JONES), who believes he's been resurrected to help stop the witchy sisters.
