This movie was suggested to me by one of my friend. And It was certainly as wonderful as I expected it to be.
It is the story of a person who has been working for many technical and computer related stuffs. While working for CIA, he came to know that theres a program which is running under the NSA which may record every single call, or a private text that someone sends, or Facebook messages, or even can access the data in your computer without your knowing. It doesnt stop like this, it can even access any web camera and watch everything they want.
All of this is going on only on the name of security but It is just not acceptable he realized. So he just revealed every truth and USA tried to arrest him and he escaped to Russia where he still lives in.
Yes, It is a real story of a wonderful person.
