Killa is a hired assassin who is also mute by choice. As a child he grew up in an orphanage and spoke with a lisp. Since that time Killer has never spoken. He spends his free time alone, watching bullfights on TV and eating seafood.
Killa has decided to get surgery to correct his speech impediment. To pay for the operation Killa is taking on hits, but he will only kill those that are rude and nasty. He then meets a bar girl who comes in and out of his life as she wishes. Killa also takes in a street kid and the three of them become an informal family.
Killa's life seems to be headed on the right track, but the last hit job turns his life upside down.
