The Faroe Islands, A.D. 894: a hungover young Thor awakens inside the mouth of a huge dragon. The She-Vikings cheer the hero who delivered them from the beast that had been tormenting the village. But that’s not how Thor remembers it. The dragon, alive and equally hungover, is named Skabgagg; Thor encountered him on the trail of the marauders and they found a band of trolls were the culprits. Slaughtering them all, the two new friends celebrated, leading to their inebriated condition. The She-Vikings investigate and confirm Thor’s tale so the feasting begins.
Three days later, Thor returns to Asgard where Heimdall warns him his father Odin is displeased. In the dragons’ realm, Skabgagg is likewise scolded by his father for consorting with humans….
A week later, Thor is again summoned to the She-Viking village where Skabgagg has returned, demanding food and drink and inadvertently killing one of the women. Thor wakes the dragon who is pleased to see his friend again. But Thor is here to punish him for his misdeeds. Skabgagg, hurt by his friend’s unexpected betrayal and offended by his judgmental tone, gives Thor the battle he is looking for….
Hours later, the dragon dead, Thor can’t bring himself to join in the celebration and quietly leaves the village for Asgard….
