This is an HBO adaptation of American author George R.R. Martin's epic fantasy novel series A Song of Ice and Fire.
The show explores a medieval-like fantasy world with its plethora of characters all struggling in the only game that matters - the game of thrones. And in this game you either win or you die, there is no middle ground.
Sorry, no info about the next episode of Game of Thrones is available yet.
