Thor takes Jane Foster to Asgard. Asgardian warriors escort a captured troll. Jane is unnerved by the sight and Heimdall’s grim expression. Thor turns Jane into a flying goddess as Odin readies for war. These changes frighten Jane and lose faith, causing her to fall. Thor saves her, urging her to be fearless, like an immortal.
Odin tests Jane’s mettle by summoning the Unknown. Jane, terrified by the monster, forgets her powers and calls Thor. Thor banishes the Unknown. Jane requests Odin to take away her powers, and he sends her back to Earth. Thor, heartbroken, is sent to Gundersheim, where a troll brings back the Unknown.
Jane arrives on Earth, waking from a dream, and starts working for Dr. Kincaid.
Thor, weakened, struggles against the creature until Sif, a childhood friend, arrives to help. They banish the Unknown. Sif’s love reignites Thor’s spirit. Odin watches, content with his plan.
