Grab some tissues because the trailer for Batkid Begins is here

The world is a horrible, cruel place. But every now and then you get a story like the one we experienced back in November 2013. It was then that 5-year-old leukemia survivor Miles Scott brought the nation together when he transformed into Batkid and saved San Francisco from comic book villains as part of his Make-A-Wish dream.

It was a touching story, to say the least, one that will be shared in the new documentary Batkid Begins. Today, the first trailer for it was released.

"Batkid Begins is a documentary that takes you back to November 15th, 2013, the day San Francisco turned into Gotham City, and the day the internet was nice. More than a billion people took to social media to cheer on BatKid, even President Obama! In all, the #SfBatKid and #BatKid hashtags reached more than 1.84 Billion people on Twitter and Instagram. This wish and this little caped crusader resonated with so many people, including us, and we wanted to find out why."

If the trailer is any indication, you're going to want to watch this emotionally charged documentary with a box of tissues near you. Batkid Begins will open in theaters in select cities on June 26.
