Gotham, fifteen years ago. Seventeen-year-old Selina Kyle is surviving alone in the East End after aging out of a brutal group home — pickpocketing, grifting, disappearing. When she falls into the orbit of Magdalena "Magda" Vassos, an aging professional thief who recognizes raw talent, she gets her first real education: how to read a mark, how to plan an exit, how to control a room. But Magda has a powerful enemy in Carver Holt, a predatory fixer who controls the East End's criminal ecosystem. As violence escalates, Selina faces choices that will define who she becomes. The final episode jumps forward to Selina at 23 — fully formed, already legendary — and reveals Magda's fate. An origin story that earns its ending.
