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.

"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.
