A cunning tactical play by King Alfred keeps Uhtred close at heel, but it's not long before Uhtred realizes he's been tricked and his relationship with the King hits a new low. King Alfred then invites Uhtred to peace talks only to use him as a pawn, handing Uhtred over as a hostage to the Danes. However, the turn of events reunites Uhtred with his Danish brother Ragnar the Younger. When the tides turn once again and threaten Uhtred's life, Ragnar proves to be a true ally and quite possibly, Uhtred's saving grace. Meanwhile, a great battle looms over Wessex.

Uhtred and Leofric lead a raiding party to Cornwall on a mission for wealth and independence. The party becomes mercenaries for a Cornish King, and Uhtred attracts the attention of a beautiful sorceress queen named Isuelt. Iseult's charms and the promise of silver make Uhtred feel like he finally has the chance of a new start. However, when he returns to Wessex he is faced with the wrath of King Alfred and a judgment that leaves both his life and the life of his best friend Leofric hanging in the balance.
