In 1970s London, during the punk music revolution, a young grifter named Estella is desperate to build a reputation for herself through her creations. She befriends a pair of young criminals who enjoy her penchant for mischief, and together they make a living on the London streets. Estella's fashion sense captures the attention of the Baroness von Hellman, a fashion legend who is both devastatingly stylish and terrifyingly haute. However, their relationship sets in motion a chain of events and disclosures that would lead Estella to embrace her bad side and transform into the noisy, trendy, and vengeful Cruella.
