Three years after the events of "WandaVision," Agatha (Hahn) remains trapped under Wanda's spell in Westview, New Jersey, where she unknowingly acts as a lead protagonist in another genre series. Similar to "WandaVision"'s format, the premiere takes on the style of a humorous and stylish premium-channel true crime parody, as if Harkness is auditioning for the next season of "True Detective." But that's not until her psyche is infiltrated by a gothic, curly-haired teen referred to only as Teen (Joe Locke), who brings her back into the real world.
