Hairy and rowdy trolls called rolleys sail to a land inhabited by more peace-loving elves. When the rolleys arrive to the elf village, they scare the elves away and settle down in the village. One of the elves, Milli, a brave elf girl, returns to the village to make a peace with the rolleys. The rolleys do not warm to Milli's peace proposal, but she becomes friends with a rolley called Rölli. It becomes their mission to solve the conflict between the elves and the rolleys.<ref name="ses"/>
