The film takes place early in the events of The Fellowship of the Ring — specifically in the gap between Bilbo’s 111th birthday celebration and Gandalf’s return to Bag End after confirming that Frodo possesses the One Ring. During this unseen period, Aragorn and Gandalf secretly hunt for Gollum before Sauron’s forces can find him first. The story centers largely on Gollum’s perspective, following his flight, paranoia, and survival as multiple powers race to track him down.
