This lesser-known version of the Camelot legend is a work shaped predominantly by Cornel Wilde, who co-produced, directed, co-wrote, and played Lancelot.

Lancelot is King Arthur's most valued Knight of the Round Table and a paragon of courage and virtue.

A sub-plot concerns Arthur's effort to forestall a challenge from a rival king, a problem that will inevitably catch Lancelot up in a personal conflict.

Though Lancelot is loyal to Arthur and Guinevere's marriage to the King takes place as planned, it is not long before the two become lovers.

Years later, Modred murders Arthur for his throne, and Lancelot returns to defeat him, thus ending the civil war that has been raging in Britain.
