Following the liberation and destruction of Efrafa, the Efrafans move into Watership Down with Moss, the highest-ranking surviving officer as their reluctant leader.
Vervain wanders about aimlessly, getting into all sorts of trouble. Bigwig, meanwhile, continues to push his Owsla. Campion, with Pipkin's help, is also beginning to regain his strength.
The Junior Owsla and Kehaar help an orphaned hawk named Scree survive, while at the same time trying to prove to Hazel they are responsible enough to go on solo patrol.
Hazel and the others notice a change in Redstone. After learning that elil and man are hunting the Redstone warren, they leave only to smell Campion's trail.
Woundwort discovers that a human construction crew plans to bulldoze Redstone.He and Vervain travel to the Warren of the Shining Wire. There, he tells Cowslip he will show him Redstone destroyed if she will give him his seer, Silverweed.
Woundwort, Vervain and Silverweed arrive at Darkhaven, just in time to meet up with Campion. At the same time, Hannah goes off to meet up with the hedge wizard in order to learn magic so she can help her friends.
Silverweed traps Fiver in a twisted dreamworld illusion, allowing him to invade Fiver's mind and see through his eyes to learn the location of Watership Down for his master Woundwort.
Bigwig uses Silverweed's influence to turn Hawkbit and Dandelion's original ideas against them when they attempt to slack off. Spartina is sent by Woundwort to befriend Hazel and the others and act as a spy for him.
The Watership Down rabbits prepare for the last battle with Woundwort, once again gathering their animal friends to aid them and setting up traps around the warren.
It's time to end the war once and for all. Both sides collide and there can be only one winner. After the first attack, both sides are injured and weakened, but they must keep fighting.
