Thadeous and Fabious are sons of King Tallious in the Kingdom of
Mourne. They are warriors: Fabious is dashing and skilled and Thadeous
is lazy and ineffectual. While celebrating his latest victory over the
evil sorcerer, Leezar, who has been ravaging Tallious's kingdom, Fabious
introduces the virgin Belladonna whom he has freed from a tower and
wishes to marry. Though his brother makes him the best man, Thadeous
skips the wedding after overhearing Fabious's Knights Elite, led by
Boremont, talk about him negatively. The wedding is then crashed by
Leezar, who reveals himself to be the one who placed Belladonna in the
tower. Leezar re-kidnaps her and flees. Returning to the castle with his
servant Courtney, Thadeous is given an ultimatum: join Fabious on his
quest to rescue Belladonna or be banished from Mourne.
Visiting the Great Wize Wizard, Thadeous and Fabious learn that
Leezar is attempting to fulfill a prophecy of a warlock having sex with a
maiden when the two moons converge, impregnating her with a dragon that
will allow him to take over King Tallious's kingdom. To destroy Leezar,
they are given a magic compass that will lead them to the Blade of
Unicorn, located within a labyrinth. On the way there, they learn
Fabious's eunuch slave, Julie, has been reporting to Leezar of their
progress and that the Knights Elite are serving the warlock. Fabious
sends his mechanical bird Simon to tell the king of the betrayal by the
Knights Elite and request reinforcements. Thadeous, Fabious and Courtney
are captured by nymphs
under their leader, Marteetee, who imprisons them at an arena, where
Fabious kills off Marteetee's finest warrior. In retaliation, Marteetee
summons a hydra-like
monster to kill them. The brothers are rescued by Isabel, a warrior
seeking revenge for her father's murder at Marteetee's hands.
Later that night, Thadeous learns that Isabel is also after Leezar
for the slaughter of her brothers. The next day, the party learns too
late that Isabel stole the compass from Thadeous. Fabious, finally
angered by his brother's selfishness, decides to find the Blade of
Unicorn alone as Thadeous and Courtney go to a tavern, where they find
Isabel and steal the compass back. But finding that his brother has been
captured by Leezar's men, Thadeous wins Isabel over as they join
forces, entering the labyrinth where they encounter a Minotaur.
After becoming separated from the others, Thadeous retrieves the Blade
of Unicorn and slays the Minotaur. Thadeous and his group make their way
to Leezar's castle and free Fabious, giving him the Sword of Unicorn.
As the others kill off Julie, Boremont's men and Leezar's three witches,
Fabious impales Leezar with the Blade of Unicorn, to prevent him from
raping Belladonna.
After their victory, Isabel leaves for another quest and the heroes
return home. Fabious and Belladonna marry, while Thadeous is approached
by Isabel, who reveals that she has fallen in love with him. However,
for them to have sex, he must first slay the witch who has cast a spell
on her, locking her in a chastity belt. Though not in the mood to go out, Isabel's suggestion convinces him to go on a new adventure.
