A lesson in morals

On the surface it is a movie about the exploitation of immigrants.
Inside it's about a young boy who has to grow up and learn hard lessons about life.

As the father uses his son to make money by smuggling in people, giving them a place to
live, getting them visas, feeding them and making them work for him all at a cost.
They have no choice and he knows it. After one of the people are killed the boy makes
a promise to the dying man to take care of his wife and child. This goes against everything
his father has taught him. So begins the dilemma.

I thought it a very powerful movie and message on the moral choices we all make.
