Unassuming hobbit Bilbo Baggins is pulled out of his comfortable life when Gandalf the wizard volunteers him for a dangerous quest. He joins a party of dwarves who are on a mission to reclaim their lost homeland, which has been taken over by a dragon. When the group journeys into the Misty Mountains, Bilbo becomes separated from the dwarves and falls into a cave, where he finds himself confronted by Gollum and forced to play a riddle game. It is set in Middle-earth 60 years before the events of The Lord of the Rings and is the first part of Peter Jackson's fantasy adventure trilogy based on JRR Tolkien's novel, starring Martin Freeman, Ian McKellen, Richard Armitage, James Nesbitt, Ken Stott, Cate Blanchett, Ian Holm and Christopher Lee
