Unmasked: Revealing the Superhero In All Of Us

It sounds like you are thinking of the classic documentary Comic Book Superheroes Unmasked, originally released in 2003 on the History Channel, which explores the profound cultural, social, and political impact of superheroes throughout American history. 

Unmasked: Revealing the Superhero In All Of Us is a Sioux Falls-based non-profit organization that honors and supports medical caregivers, specifically those in the NICU (Neonatal Intensive Care Unit) and PICU (Pediatric Intensive Care Unit).
