In the third installment in the series, Dar, the Beastmaster (Marc Singer) teams up with Seth (Tony Todd) to rescue his brother King Tal (Casper Van Dien). They learn that the boy was captured by the evil Lord Agon (David Warner (actor)), who has been sacrificing young prisoners in order to magically retain his youth, and seeks to gain immortality by releasing the dark god Braxus from his prison. Along the way, the heroes are assisted by a beautiful witch named Morgana (Lesley-Anne Down), her acrobatic sidekick Bey (Keith Coulouris), and a warrior woman named Shada (Sandra Hess).
