Batkid for a day

A young leukemia patient has a wish and Make-a-Wish is going to make it happen.  5-year-old Miles wanted to be a superhero for his wish.  The city of San Francisco is going to make it a reality on November 15.  His day will start with a tv message from the Police chief asking if anyone knows where Batkid is because the chief needs his help.  Miles will be rescuing a damsel in distress, capturing the Puzzler, and saving a mascot from being kidnapped.  At the end of the day, he will be thanked  and cheered-on by a large crowd and given a key to the city.  This is the first time that Make-a-Wish is asking for volunteers to help.  They're expecting a huge turnout.  Miles' parent know about the day but Miles has no clue except that he's going to be getting a costume.  hero for a day
