(NBC News) At some point in their life every little boy dreams of being a super hero.
On Friday an entire city of heroes will make one little boy's dream come true.
Miles, 5, has been battling leukemia.
He's in remission now, and when the Make-A-Wish Foundation asked what would make his recovery a bit easier, he said he wanted to be Batman.
It started with a few e-mails, then a few more.
Now, thousands have volunteered to turn downtown San Francisco into Gotham City, setting the scene for Miles to rescue someone on a cable car, stop a bank robbery in process and then stop a kidnapping.
"People are flying in, some teachers are bringing their classrooms, I'm overwhelmed," says Patricia Wilson, Executive Director of the Make-A-Wish Foundation for the San Francisco Greater Bay Area.
It's a super-human effort for a kid who at 5 has already taken-on the toughest villain there is.
"Obviously we'll never replicate this, this is just a moment in time of something goes viral and a city comes alive," Wilson says.
