A five–year–old boy with leukemia got his wish fulfilled on a big scale.
Thousands of people turning out in San Francisco to help mild–mannered Miles Scott become "Batkid" for the day.
Miles was diagnosed with leukemia when he was just a year old.
He's now in remission and the make–a–wish foundation is helping his dream come true – by turning the city into Gotham City for a day!
He rescued a woman from cable car tracks in Nob Hill and captured the Riddler in the act of robbing a downtown bank.
He even rescued the San Francisco giants mascot who was kidnapped by the penguin.
