About the life and adventures of a gang of abandoned street kids known as "Capitães da Areia" (Captains of the Sands), in Salvador, Bahia, during the 1950s.

A retired army sergeant, a police officer and his wife and a drug dealer apparently have nothing in common, but they will unite for a greater good. When people start using explosives to fish on the edge of Salvador, Bahia, this group will do everything to end this environmental crime. But in the search for the paths that seem most correct, each one of them will go through more personal and moral conflicts.
