The show follows five girls – Will, Irma, Taranee, Cornelia and Hay Lin – who have respective magical powers over the classical elements quintessence, water, fire, earth and air, which they use to fulfill their duties as Guardians of the Veil. The names of these five characters form the titular acronym, despite the characters not actually being witches. The show takes place in the fictional city of Heatherfield and various mythical worlds, primarily Meridian.
