With King Uther's sudden death, chaos threatens to engulf Britain. The sorcerer Merlin has visions of a dark future and installs young and impetuous Arthur, Uther's unknown son and heir raised as a commoner, as the new king. The two install themselves in Castle Camelot with their allies, which include Arthur's biological mother, his foster brother, and a quartet of loyal warriors. From Camelot, Arthur tries to build a new and better Britain, where people can live in peace.
Meanwhile, Arthur's cold half-sister Morgan plots to take the crown from him.

Uther's daughter Morgana returns from banishment and poisons her father. Merlin arrives too late to save the king but gets Uther to acknowledge his illegitimate son on his deathbed…
