[4][5] Erik, a young Viking, discovers that he has no taste for rape and pillage, and suffers guilt over the death of an innocent woman, Helga.

Erik learns from the wise woman Freya that Fenrir the wolf has swallowed the sun, plunging the world into the age of Ragnarök.

Arriving at Hy-Brasil, Erik and crew are astonished to find it a sunlit land where the people, who dress like ancient Greeks, are exceedingly friendly and hospitable (if musically untalented).

Aud has warned the Vikings that should blood ever be shed upon Hy-Brasil, the entire island would sink beneath the waves.

Erik sounds the second note to awaken the gods, and he and his crew climb a path made of stars to approach the great Hall of Valhalla.

Odin persuades Fenrir to spit out the sun, but tells Erik that the end of Ragnarök will not bring peace to the world.

Some of the crew who died earlier in the adventure attempt to save them, but even as they are drawn into the Pit, they hear the Horn Resounding's third note, blown by Harald, who had returned to the ship, which flings them clear.

As the villagers celebrate Erik's return and Halfdan's defeat, the sun rises, ending the age of Ragnarök.

[11] Vincent Canby of The New York Times gave it 3 out of 5 and wrote: "Doesn't measure up to the best of the Python films, but it consistently entertains through the occasional gags that do not work and dialogue that is sometimes obscured by sound effects.

"[12] Roger Ebert of the Chicago Sun-Times gave the film 0 out of a possible 4 stars, calling it "An utterly worthless exercise in waste and wretched excess, uninformed by the slightest spark of humor, wit or coherence.

"[13] Chris Willman of the Los Angeles Times gave it a negative review, and called it "A stillborn comedy in which minutes sometimes mysteriously go by between even attempted gags, and in which virtually no comic scene works up to any kind of viable punch line or payoff.
