Arturo Zamora is like most of 13 year old boys. He has two quirky best friends (one who likes to pretend he is Pitt Bull and one who likes to point out how ridiculous that is), a crush on a girl named Carmen, and a summer job washing dishes at his family's restaurant. It all seems like this will be a pretty regular summer, until a slick developer named Wilfrido Pipo comes into Arturo's Miami neighborhood with talk about a new apartment complex. When Arturo and Carmen dress up in disguises to investigate shady Wilfrido, they learn that this new development is worse than they thought - this new development will tear down the Zamora family's restaurant. With the city council voting on Wilfrido's request for the restaurant's lot, the Zamora family is concerned and willing to fight to keep their family business.
