Tsotsi
(2005)

Tsotsi (Presley Chweneyagae) returns the baby boy to his wealthy parents, and is immediately arrested by the Police afterwards.

There are, also, two other alternate endings, available on the DVD:
-One, in which, after he knows he is arrested, he gets his hands in his pocket, an officer believes he tries to retrieve a gun, alerts everyone, and Tsotsi is shot and killed.  It turns out he was trying to get a crystal baby bottle, which drops to the floor and breaks.

-And another one, in which everything happens just as in the previous ending; however, Tsotsi survives his gunshot wound, and manages to escape by jumping a hedge and running off.
