A warren of rabbits is living a happy and peaceful existence until one, Fiver, has a vision of a catastrophe about to befall it. His brother, Hazel, convinces a group of rabbits to leave the warren and follow him. They are seeking a safer place to live but the journey to safety is beset on all sides by danger, sometimes from the least expected sources. However, thanks to Fiver, they also know their destination: Watership Down.
