What begins as an exciting trip quickly turns into a struggle between life and death.

When a group of friends spend their summer in Western Norway, Arthur shows them a mysterious valley no one has stepped into since the Viking Age. Most don’t take him seriously, until Harald discovers runes warning of a doomed voyage to the land of trolls.

Driven by his hunger for adventure, Arthur persuades them to row out to sea. After a day, they reach an uncharted island and quickly discover they are not alone.

When fear takes hold and the island tears them apart, their friendship shatters. Forced onto separate paths, they must face new dangers and fight to survive. As homesickness grows and hunger torments them, they begin to wonder if they will ever see their loved ones again.
