Falco stars as the title character Jackie O'Hurley, who is described as "a strong-willed and brilliant — but very flawed — emergency room nurse in a complicated New York City hospital. A lapsed Catholic with an occasional weakness for Vicodin and Adderall to get her through the days, Jackie keeps the hospital balanced with her own kind of justice. Every day is a high wire act of juggling patients, doctors, fellow nurses and her own indiscretions."
Falco has appeared on Broadway in Frankie & Johnnie in the Clair de Lune, 'night, Mother and Side Man.
Falco will return to the New York stage in May opposite Alison Pill will in the Naked Angels production of Chloë Moss' This Wide Night.
