Written by Aguirre-Sacasa and Michael Grassi and directed by Maggie Kiley, Katy Keene follows the lives and loves of four iconic Archie Comics characters — including fashion legend-to-be Katy Keene and singer-songwriter Josie McCoy (Ashleigh Murray) — as they chase their twentysomething dreams in New York City. The musical dramedy based on the Archie Comics chronicles the origins and struggles of four aspiring artists trying to make it on Broadway, on the runway and in the recording studio.
