Following his battle with Seidring, Thor has been put to bed and given the best medical attention that Asgard offers; however, he remains near death. Odin checks on his son's current condition and feels guilty as Thor's condition is at least partially because Odin had halved Thor's strength before the battle with Seidring. Returning to his throne room, Odin has Seidring brought to him, and as punishment has Seidring transported to the realm of the Rock Trolls, who take Seidring to be the king of their barren world.

While in California, Hercules is taken to the set of a new Hercules movie being made by Stardust Studios, the Prince of Power is completely unaware that this studio is, in reality, a front made by Pluto and Hippolyta. They hope to trick him into signing an Olympian Pact. Under the guise of Stardust Studio owner J.P., Pluto has Hercules do a screen test by fighting a mechanical giant. Pluto rewards Hercules by passing the "test" by giving him a large feast.

Back in Asgard, Thor beings his recovery; even though he's still confined to a bed, Thor is taken out to the frozen sea of Marmora by Balder to do ice fishing. However, the outing is marred when Thor misses one of his targets- a gigantic amphibian creature- and attacks their boat, forcing Balder to fight it off and flee the scene.

While back on Earth, Hercules is asked to sign a contract for the movie deal during his feast. Hercules brashly signs the document, and Pluto reveals his true self and explains that Hercules has signed an Olympian Pact. Both Pluto and Hippolyta boast about how Hercules blindly signed a contract to take over the role of ruling Hades for all eternity.

As Hercules is forced to fight Pluto's hordes, Thor has fully recovered in Asgard and requests Odin to allow him to return to Earth so that he might have a rematch against Hercules. Having put aside his differences, Odin agrees to the request and sends Thor to California, where he finds Hercules battling the hordes of Pluto. Seeing his rival fighting overwhelming odds, Thor decides to lend a hand and jumps into the battle fighting with Hercules side-by-side. Observing the battle, Pluto and Hippolyta boast about their victory and teleport away, having accomplished their goal.

When the two finally defeat the horde of attackers, Hercules tells Thor what has happened, and understanding Hercules' fate, Thor decides that there isn't time for their final battle and departs.
