Thor's disruption-of-communism-intermission having concluded, he thus prepareth to return to Odin and prove that Loki cheated during the trial of the gods.
Unfortunately, Thor runs across a big game hunter (no, not that big game hunter) and is felled by, well, a sleeping pill. Kind of disappointing to find out that you can fell a Norse god with a blowgun, but anyways, our story continues. Thor fights a robot created by Odin called the Destroyer, who is awakened by the interference of Loki (obviously). The Destroyer is a rather bland villain, although he is able to throw Thor's hammer.
Alas, Loki has outsmarted himself, as if Thor is killed by the Destroyer, he knows Odin will eventually find out it's his fault, and no one wants a PO-ed Odin. So Loki must try to save his brother.
The issue ends on a cliffhanger, with Thor trapped in the floor, and Loki trapped in the dungeon of No-Escape (yes, that's actually what it's called).
In the backup story, Thor prepares for his quest to discover who broke Odinsword.
