"Kilas" (a Portuguese misrepresentation of the English word "killers") is the nickname of a petty con-man who gets involved with a deadly ring of spies.

Pedro is a young agricultural worker who gets caught in the middle of a fight between two families, kills a man and escapes to the capital. He can't find work,resorts to begging, but keeps his mountaineer pride. He starts a new life with a prostitute who is nice to him, but nothing works. He returns home, and alone, and now he finds life there is sad as well.

Supported by the works of poet/musician Claude Miller, the film portraits a snippet of brazilian reality.
