LIVE UPDATES: Batkid's Make-a-Wish Transforms San Francisco Into Gotham

A little boy will get the surprise of a lifetime today when San Francisco transforms into Gotham City to fulfill the 5-year-old leukemia patient's wish to be Batman for a day.

The Make-a-Wish Foundation has created an entire day catered to Miles' dream.

Miles' day will include seeing a breaking news story on a TV. The police chief will be asking whether anyone knows where Batkid is because he needs his help to solve a crime and "bringing the bad guys to justice," Make-a-Wish said in a statement.

He'll spend the afternoon rescuing a damsel in distress tied up across the Hyde Street cable car line and capturing the Puzzler in the act of robbing a downtown vault. As Batkid eats his lunch at Burger Bar, he'll get a special message from the chief, telling him to go to the window where he'll look out over Union Square and see a huge group of volunteers jumping up and down and asking for his help.

A villain will be kidnapping a famous San Francisco mascot and Batkid will rush to the rescue. His last stop will be City Hall, where the mayor and police chief will thank him and present him with a key to the city and a crowd will be cheering him on.
