Ian Mune as a Bounder in the New Line film
Bounders were members of the police force in the Shire. They guarded the Shire's borders. They would ask newcomers what business they had in the Shire. It was rare that any newcomers came through. However, in 3018, Sauron's Nazgul entered the Shire. They were searching for the Ring of Power, which was owned then by Frodo Baggins. A bounder scolded the Nazgul for entering, but they killed him. This event made the other bounders worry, so they kept an extra close watch on the rode. During the War of the Ring, Bounders guarded the gates of Buckland by orders of the evil wizard Saruman.
