Background

Well, I wanted to give beginners or strangers a little background on The Hunger Games. But I won't tell any detail that may discourage anyone of watching the movie or reading the book.
Well, after some sort of apocalypse, what once was North America has become the nation of Panem. There are 12 states or "districts" ruled by the Capitol. Although there was a rebellion against the Capitol, it failed and it came to pass a new law in order to avoid any new rebellious movement. Each year, each district must offer two young people, a girl and a boy, from 12 to 18 years old as "tributes" to compete against each other. From the 24 tributes, only one survives. From district 12, Primrose Everdeen is elected but her sister Katniss volunteers herslef to save her sister. Curiously, the male tribute is Peeta Mellark, who is secretely in love with Katniss.The whole event is televised on every district and watching it is compulsory to remember everyone the consequences of rebellion.The rest of the story is up to you, you decide wheter to stay with the doubt or you go buy the book or even cheaper, a ticket for the movie.
