(CNN) -- Get your tissues ready.
Warner Bros. has released the trailer for "Batkid Begins," which threatens to make you feel all of the feels.
The documentary tells the story of Miles Scott, who was a 5-year-old leukemia patient in November 2013 when the city of San Francisco helped the Make-A-Wish Foundation make his dream come true: He was a superhero for a day. Thanks to social media, the story resonated around the world and even got President Obama involved as Miles fought bad guys and saved "Gotham."
The trailer includes his father explaining why Miles so strongly identified with Batman.
"One of his doctors told us that with this disease, they just become, like, a fighter," the elder Scott said. "They fight for life. I think he sees the good vs. evil battle in superheroes."
The trailer will help you relive what many called the feel-good story of the year. But don't take our word for it.
Miles' leukemia was in remission as of November.
According to Variety, the story of Batkid may get double love from Hollywood, as Julia Roberts is reportedly set to produce and star in a feature film adaptation of the documentary.
Warner Bros. is owned by the parent company of CNN. "Batkid Begins" opens in selected theaters on June 26.
