Game of Thrones is based on the novel A Game of Thrones by George R R Martin. Lord Eddard Stark is summoned to court by his old friend, King Robert Baratheon, to serve as the King';;s Hand. Across the narrow sea in Essos, the exiled Prince Viserys Targaryen forges a new alliance to regain the Iron Throne. But in a land where seasons can last a lifetime, winter is coming...and beyond the Great Wall that protects them, a forgotten evil has returned.
The main accomplishment of Game of Thrones is that, while it should keep the hard-core fans satisfied, even viewers who don't care whether Theon is a Greyjoy or a Tully can play along and have a good time.
