In 1003 AD, along the west coast of Norway, Lord Harald Jaekelsson and his Vikings raid the town of Lakstad. After having their way with the women and killing nearly all the villagers, they decide to leave for the New World. But the town wise man, the last survivor, with the help of a runestone, places a curse on them. He pleads with the gods that they never reach their destination. Harald takes a bow and shoots the wise man dead, and they sail on. They sail for 1000 years, until they finally land at the South Street Seaport in New York. They are not human any more; they are powerful zombies. They kill everyone they encounter, and are about to have fun with a woman when Thor shows up.

In Norse mythology, Thor (from Old Norse Þórr) is a hammer-wielding god associated with thunder, lightning, storms, oak trees, strength, the protection of mankind, and also hallowing, healing, and fertility. The cognate deity in wider Germanic mythology and paganism was known in Old English as Þunor and in Old High German as Donar (runic þonar ᚦᛟᚾᚨᚱ), stemming from a Common Germanic *Þunraz (meaning "thunder").

Ultimately stemming from Proto-Indo-European religion, Thor is a prominently mentioned god throughout the recorded history of the Germanic peoples, from the Roman occupation of regions of Germania, to the tribal expansions of the Migration Period, to his high popularity during the Viking Age, when, in the face of the process of the Christianization of Scandinavia, emblems of his hammer, Mjölnir, were worn in defiance and Norse pagan personal names containing the name of the god bear witness to his popularity. Into the modern period, Thor continued to be acknowledged in rural folklore throughout Germanic regions. Thor is frequently referred to in place names, the day of the week Thursday ("Thor's day") bears his name, and names stemming from the pagan period containing his own continue to be used today.

The term Viking (from Old Norse víkingr) is customarily used to refer to the Norse explorers, warriors, merchants, and pirates who raided, traded, explored and settled in wide areas of Europe, Asia and the North Atlantic islands from the late 8th to the mid-11th century.

These Norsemen used their famed longships to travel as far east as Constantinople and the Volga River in Russia, and as far west as Iceland, Greenland, and Newfoundland, and as far south as Al-Andalus. This period of Viking expansion – known as the Viking Age – forms a major part of the medieval history of Scandinavia, Great Britain, Ireland and the rest of Europe in general.

Popular conceptions of the Vikings often differ from the complex picture that emerges from archaeology and written sources. A romanticised picture of Vikings as Germanic noble savages began to take root in the 18th century, and this developed and became widely propagated during the 19th-century Viking revival. The received views of the Vikings as violent brutes or intrepid adventurers owe much to the modern Viking myth which had taken shape by the early 20th century. Current popular representations are typically highly clichéd, presenting the Vikings as familiar caricatures.
