Jack the Giant Killer

Pendragon rules over giants, witches, hobgoblins and other dark creatures in the Duchy of Cornwall. The wizard Herla defeats him and exiles him to an uncharted island. After Herla's death, there is no longer a defense against Pendragon, who vows revenge.

Years pass and the kingdom celebrates Princess Elaine's crowning by King Mark. Pendragon arrives disguised as Elidoras and presents Elaine with a music box containing a miniature dancing jester.

That night the music box releases the tiny jester, which grows into the giant Cormoran that abducts Elaine. Guards are powerless to stop the creature, and Pendragon carries Elaine away to his ship.

A brave farmer named Jack confronts Cormoran and frees Elaine, slaying the giant. Grateful, King Mark knights Jack and names him Elaine's protector.

King Mark orders Jack to escort Elaine to a convent across the sea for safety. Lady Constance, bewitched by Pendragon, betrays the plan by revealing it to Pendragon.

Demonic witches are sent to intercept the ship. The captain is murdered, Elaine is captured, and Jack and Peter are cast overboard as chaos erupts.

Pendragon bewitches Elaine into an evil witch loyal to him and returns to Cornwall to confront King Mark. He gives the king one week to renounce the throne or Elaine will be killed.

Lady Constance's betrayal is revealed when King Mark discovers her witchform; he smashes the mirror to free his realm from Pendragon's spell.

On the sea, the Viking Sigurd rescues Jack and Peter and meets the Imp, a leprechaun imprisoned for crafting seven-league boots. The Imp explains that three wishes can be granted by his gold coins if used by an honest person.

The Imp guides Jack to Pendragon's island; with the first two wishes, Jack frees Elaine from captivity, unaware that she has been transformed into an evil witch by Pendragon.

On the journey home, Elaine gives Jack a sleeping potion and, when she touches the Imp's bottle, her malice causes it to heat and she casts it into the sea, destroying the bottle. Pendragon captures Jack and tries to coerce him by transforming Peter into a chimpanzee and Sigurd into a dog.

Jack, aided by Peter and Sigurd, breaks free from Pendragon's trap and smashes Elaine's mirror reflection to break the spell. They flee as Pendragon conjures a two-headed giant.

The Imp's bottle washes ashore, and he grants the final wish: a sea monster rises to kill the giant. Pendragon then transforms into a dragon and attacks the ship.

Jack defeats Pendragon in battle, the castle collapses crushing Garna and the witches. Sigurd and Peter are restored to humans, the Imp is freed, and his boots return him to Ireland, while a rainbow guides Jack and the others home to Cornwall.
