From Icepeak, Queen Yorey and King Bugobbi send forth a wave of glaciers, forcing Happy Valley Dinosaurs to retreat south.

Bugobbi caps the volcano with glaciers, a ruse allowing subhuman troops to abduct Princess Elena, a bride for Bugobbi.

Elena escapes and meets the great warrior Adelaide. They grow close but are separated when Adelaide is attacked and Elena recaptured.

Elena escapes again, but encounters Gisela and Otter. They capture her, planning to use her as a bargaining chip.

Prince Bugobbi II refuses to marry Elena, but keeps her as a hostage. Meanwhile, Adelaide encounters Dark Lion, a masked warrior.

Adelaide and Dark Lion infiltrate the castle, but fail to rescue Elena. They escape, planning their next move.

King Barroni sends his son, Prince Philip, to Icepeak to negotiate Elena's release. Adelaide stows away on their ship.

Yorey insults Elena and Philip, inciting Philip to attack. Adelaide infiltrates the castle again but is saved by Dark Lion.

With the help of the dragon and hawk riders, they assault the fortress, melting the Ice walls with dragon fire.

Philip and King Barroni rescue Elena from Yorey. He opens the volcano's caps, causing a cataclysm that obliterates Icepeak and the subhuman army.

Prince Philip and Elena barely escape, sharing a kiss atop a cliff. Dark Lion watches them, then disappears.

The Dinosaurs return to Happy Valley. Philip shaves, cuts his hair and puts a suit on to celebrate their wedding in the palace, marking the end of their ordeal.
