The interpreter!

I am going to take profit of the film we have watched with the English teacher Joan Carles, the interpreter.

All the story began when Silvia Broome, an interpreter born in Africa who works for the ONU, listens to a mysterious conversation. In it, she understands that a criminal organization wants to kill the President of the republic of Matobo. After listening to these whisperings, the life of the main character makes a radical change.
At this moment appears, Mr. Keller, a policeman whose objective consists on protecting the live of the interpreter. But he notices that Silvia is hiding some important information. Later, he knew that she grew up in Matobo and that she was a militant of a guerrilla who fought against Edmond Zuwanie (the President). Moreover, most of her family was killed by the soldiers of Zwanie.
When Mr. Keller discovers all of these things, he began to suspect about her intentions.
Lastly, when Edmon Zuwanie arrives at the ONU building, a killer tries to kill him but he failed. After that, they move the president to a safe room where there was Silvia.

She has the chance to kill the dictator accused from genocide, but after listening to Mr. Keller words, she decides not to do it.
