Thrym, the mighty Ice King of Jotunheim, has stolen Mjölnir. In exchange for its return, he demands Freya’s hand in marriage. Freya has other ideas. It’s up to Thor and Loki to find a way to retrieve the hammer. Of course, the God of Mischief has a trick up his sleeve. Thor will disguise himself as Freya and enter the kingdom, steal the hammer and sneak back out – which isn’t as easy as it sounds.
