“It shows that humanity is essentially good and not bad. In this day and age, there’s so much negativity on social media and there’s so much cynicism in the way we communicate, but this was a cause of using social media for good. That was what caused this modest wish to become a phenomenon,” she said.

The documentary follows the journey of young Miles Scott, who was granted his Make-A-Wish Foundation request to be Batkid for a day. He was diagnosed with lymphoblastic leukemia at 18 months old.

The story quickly gained traction on social media and on November 15, 2013, San Francisco was turned into a fictional Gotham City for the day. Young Miles took part in several crime scenarios, saving the city from villains like The Riddler and The Penguin. The streets of San Francisco were packed, with people following Miles from adventure to adventure. President Obama even tuned in, sending his own message to Miles via social media.
