When a seer from one tribe predicted his birth at Redwall Abbey, Sawney Rath the ferret, leader of the Juskarath, sets out to capture the Taggerung.
In Mossflower Woods, Rillflag, a European otter from Redwall is completing a birth ritual with his newborn son, Deyna, when Sawney Rath and his tribe of vermin ambush him.
To aid him in his quest, Gruven recruits a small band of vermin including Vallug Bowbeast, the deadly assassin, and Eefera, a high-ranking weasel, to continue the hunt for the Taggerung.
They, being better trackers than Gruven, decide to follow the Taggerung and kill him, to bring his head back to the tribe and claim leadership over the Juskas.
He's then released on impulse by the assistant cook Broggle when the Juska, Eefara and Vallug, who have now captured Gruven and the other vermin, are threatening to kill Nimbalo, but then their plans go wrong.
Deyna's quest is not quite over, however, as the fox Ruggan Bor, now commanding the remnants of the Juskazann tribe as well as followers of his own, the Juskabor, shortly arrives to attack the stronghold of Redwall Abbey.
As chance may have it, however, the badger ruler of Salamandastron, Russano the Wise, arrives in time to fend off Bor's attack, sending him and his vermin crew crawling on their bellies off into the sunset.
Russano then takes a medal from around his neck and drapes it over Cregga Rose Eyes's grave, as she was his adoptive mother many seasons before this terrible battle happened.
