Sixty years on, Bilbo celebrates his 111th birthday in the Shire, reuniting with his old friend Gandalf the Grey. Bilbo reveals he intends on leaving the Shire for one last adventure and leaves his inheritance to his nephew Frodo, including the Ring. Gandalf investigates the Ring, discovering its true identity and warns Frodo. Learning Gollum was tortured by Orcs and told them that Bilbo took the Ring, Gandalf instructs Frodo to leave the Shire, accompanied by his gardener Samwise Gamgee. Gandalf rides to Isengard, meeting fellow wizard Saruman the White, but learns he is in league with Sauron, who has unleashed the Ringwraiths to find Frodo. After a brief battle, Saruman imprisons Gandalf. Frodo and Sam are joined by fellow Hobbits, Merry and Pippin, and they evade the Ringwraiths, arriving in Bree where they are meant to meet Gandalf, but are instead aided by a ranger named Strider, a friend of Gandalf's who escorts them to Rivendell.
