The title is street slang for "gangster" or "thug" (Tsotsi-Taal is a local patois spoken in many black townships around Johannesburg). In this film, based on the only novel ever written by South African playwright Athol Fugard, the term also refers to the title character, who, either intentionally or unintentionally, has erased his given name and his early life from his memory, and now goes simply by Tsotsi. Unwilling or unable to recall the pain of his own childhood, he finds it impossible to feel compassion for others.
Unprepossessing physically, save for his cold, expressionless eyes, Tsotsi (played by Presley Chweneyagae) rules his small street gang with an iron fist. The group consists of the even more cold-blooded Butcher (Zenzo Ngqobe); a dimwitted misfit, Aap (Kenneth Nkosi); and Boston (Mothusi Magano), the only one among them with any education -- or conscience. When Boston expresses misgivings over the killing of a robbery victim, an enraged Tsotsi beats him almost to death.
Later that same night, Tsotsi carjacks a woman who has left her car running in the driveway while she opens her front gate. When she resists, he shoots her. He's several miles down the highway when he hears a baby crying in the back seat.
The infant calms down when Tsotsi looks at him, and without knowing why, the surly young man takes the child with him and flees. He tells no one that he has the baby, making excuses to prevent his gang from entering his one-room shack. Tsotsi quickly grows attached to the child, but realizes he's not equipped to care for it. So he spots a young mother at the village water pump and follows her home, forcing her at gunpoint to breast-feed the infant. He returns to her again and again, and his continued exposure to the kind, maternal Miriam (Terry Pheto) triggers memories of his own brutal childhood. And for the first time, he begins to question his propensity for violence.
Tsotsi works on myriad levels: as a hard-hitting and violent depiction of those living on the margins of society; as a taut, tense drama; and as a classic tale of redemption. Among a uniformly strong cast, Chweneyagae and Pheto are particularly notable. Pheto's subtle, completely convincing performance -- as well as her Madonna-like presence -- are anchored in an almost tangible emotional veracity. Chweneyagae, who has no formal dramatic training whatsoever, is so in tune with his character that he seems to be drawing from his own life experiences.
Without giving away the film's ending, suffice it to say that writer-director Hood has come up with the perfect closing scene. While it differs from Fugard's novel -- indeed, the screenplay digresses in several minor ways, and Hood has updated the story from the 1960s -- the changes ring completely true.
