This is an old timey tale about a young boy named Nikolas (Henry Lawfull) who lives in the woods with his father Joel (Michiel Huisman) in long-ago Finland. At Nikolas’s request, Joel frequently retells a story about a young girl named Lumi and her journey to a magical land called Elfhelm. This idyllic life is interrupted when the king (Jim Broadbent) orders the hardiest villagers to travel beyond the borders of their kingdom to bring back something that inspires hope. Whoever does so gets a reward—and Joel knows his family of two needs the dough.
Joel sets out on a mission to find this vague idea of hope, leaving Nikolas in the “care” of his truly terrible aunt Caroltta (Kristen Wiig). But when days turn into weeks and there’s still no sign of his father, Nikolas decides to set out and find him and Elfhelm. The kid brings his trusty pet field mouse Miika along and begins his epic quest.
