Cedric and Isaac with their caravan are captured by the Normans and taken to Torquilstone Castle. De Bracy recognises Ivanhoe but stays silent for the moment. At the castle, Rowena is reunited with Ivanhoe. Elsewhere, the Black Knight is allied with Locksley and his men to besiege the castle.

Preparations are being made to storm Torquilstone Castle. A ransom note is delivered and a plan is hatched to free Cedric while at the same time learn the defences of the castle. Athelstane regrets a deal with the Normans while Rebecca continues to tend the injured Ivanhoe. The assault on the castle begins.

The Black Knight and Cedric lead the assault on the castle aided by Urfried on the inside who exacts her revenge on the Normans. Rebecca and the injured Ivanhoe are still prisoners. Cedric and Ivanhoe are briefly reunited and Sir Brian escapes with an important hostage. Ivanhoe also disappears but Malvoisin is on his trail.

A fortunate interruption saves Ivanhoe. Sir Brian seeks refuge for himself and Rebecca at Templestowe Abbey even though women and especially non-Christians are forbidden and the Grand Master is arriving shortly. The Normans trailing the outlaws are intercepted and Cedric and Rowena set off for Coningsburgh. Isaac makes a deal to rescue Rebecca.

Rebecca is found guilty and awaits her fate. The Black Knight reveals his identity to all and Prince John is exiled to Aquitaine. Sir Brian considers a way out for himself and Rebecca but the Preceptor has another solution. The Saxons gather at Coningsburgh for Athelstane's funeral. On the day of Rebecca's execution a knight rides to the rescue and Sir Brian realises that at the end of the joust, either he or Rebecca will have a way out.
