Agatha All Along picks up after the events of Marvel's WandaVision in 2021, in which Harkness is defeated by Wanda Maximoff (Elizabeth Olsen), stripped of her magical powers and destined to live out her life as Agnes in Westview.
Here's the synopsis: The infamous Agatha Harkness is in trouble after the suspicious goth Teen helps free her from a warping spell. Her interest is piqued when he begs her to take him on the legendary Witches' Route, a magical series of trials that, if survived, rewards a witch with what he lacks. Together, Agatha and this mysterious Teen form a desperate group of witches and head down, down, to The Road.
Marvel's WandaVision head writer Jac Schaeffer serves as showrunner and directs the pilot episode.
In addition to Hahn, Agatha All Along also stars Joe Locke, Sasheer Zamata, Ali Ahn, Maria Dizzia, Paul Adelstein, Miles Gutierrez-Riley, Okwui Okpokwasili, Debra Jo Rupp, Patti LuPone and Aubrey Plaza.
Kevin Feige, Louis D'Esposito, Brad Winderbaum, Mary Livanos and Schaeffer executive produce the series. Directors for the series are Rachel Goldberg and Gandja Montiero.
