Tam, Nina, Chiz, Hooley Dan and another outlaw leader seek for Tam and Nina's parents in the dungeons of Iron Castle. Everything goes wrong, except for one vital discovery-that the power of the Wolf-King and his army depends on the extraordinary magic of the Wolf-King's crown. By capturing the crown, Tam and Nina save the two outlaws and their parents from execution, and bring an end to the tyranny of Wolf-Kingdom.
