Commissioner Gordon waits for an informant outside the ZΩrbΛs. Unbeknownst to him, however, the informant, Yanni Stavros, is being chased by a couple of thugs. They inform him that his meeting's been cancelled and they chase him towards their boss. He is finally cornered in an alley filled with old tires. The boss comes out of his car and Stavros pleads with him. However, his words make the boss even angrier that he defied him, forced him to come to the mortal coil, and then claims that he doesn't know what he thinks. He condemns Starvos to Tarturus and a bolt of electricity strikes.
Gordon takes Stavros to the hospital where he is diagnosed as being struck by lighting and only alive due to the tires absorbing the shock. Gordon is skeptical of the diagnosis as it was a clear night. Later, Gordon takes Stavros' file to Batman and the two talk about his past record of selling shipping schedules to hijackers. As a scheduler for Maximillian shipping lines he is well suited to this kind of work. Gordon then tells Batman that Stavros was going to tell Gordon about a new energy weapon capable of firing bolts of lightning. The weapon has been stolen and Batman fears that it may already be in the wrong hands. He heads out to see Maxie Zeus, owner of Maximillian Shipping.
On top of Maxie's office building (made to look like a Greek Temple) Maxie's assistant, Clio, tells Maxie about a case that's being built against him. Maxie (who is dressed like the Greek god Zeus) doesn't much care claiming that he's bored with tales of human concerns. Clio is upset that Maxie is acting like he's a god who thinks she is a muse of history. She tires to talk some sense into him but he will not hear reason. Just then, Batman arrives in the batwing. Zeus sees him and decides that this is Hades. Clio tries to tell Maxie that "Hades" is really Batman, but Zeus refuses to listen claiming that no mortal could make it to the top of Olympus. He sends Clio away and talks with Batman. Batman asks Zeus about the electron cannon but Zeus claims he has no need for mortal weapons as he can summon thunderbolts of his own, revealing that he has a lighting staff capable of generating thousands of volts of electricity. Upset that reality is starting to enter into his world, Zeus tells Batman to leave and activates guns in his decorative stone harpies. Batman gets the message and leaves. After "Hades" leaves, Zeus reveals to his thugs that he has the electron cannon and will now cause mortals to tremble, "at the fury of Zeus reborn!"
Clio returns home and cries over her Boss' condition when Batman arrives. She explains that Maximillian Shipping started losing business and to save it, Maxie started handling cargo for the mob. However, the pressure and tensions became so great that he got confused and now lives inside a fantasy. Batman asks Clio to take him to Zeus so that he can be helped and she agrees. Clio drives Batman into the company building and heads up in an elevator. Unfortunately, Zeus' thugs capture her and take her to their boss.
On top of the building, Zeus sees a police blimp and believing they're trying to encroach on Mt. Olympus, he fires the electron cannon onto it setting the blimp on fire. Clio runs up to him and tries to talk to him into reality. For a moment it seems to work and Maxie is returned. However, he soon falls back into his delusions and claims that Clio is no longer fit to be around him. He orders his thugs to tie her to the cannon. Meanwhile, Batman sneaks into the buildings but security systems detect him.Discovering him, Zeus activates a trap door and drops him into a room filled with traps. First, Zeus releases his "hydra" a python that tries to squeeze Batman to death. Batman is able to spray it with a sedative and it falls to sleep. Next, Zeus releases a warthog that Batman manages to harness with a rope. However, the warthog is too strong for him to stop and Batman is hurled through the window out of the building. Fortunately, Batman manages to catch the ledge of the building.
On the top of the building, Zeus prepares to fire the electron cannon with Clio on it. Before he can fire it, Batman arrives and stops the firing procedure. Zeus orders his henchman, Alexander, to take on Batman but he hesitates. Zeus takes this as a sign of defiance and activates his harpies having them fire on Batman and Alexander. Batman manages to destroy the harpies and Zeus attacks him with his lighting staff. Batman easily beats Zeus and deactivates the cannon. Unfortunately, Zeus fires his staff at Batman pushing him off the building, and then activates the cannon again. Batman climbs back onto the top of the building and grabs Zeus' staff. Hurling it into the cannon, he deactivates it. Zeus dives after the staff and is electrocuted when it overloads. He then falls onto a ledge and is knocked out.
Later, Zeus is taken to Arkham where he equates the inmates with the Greek gods. Although locked up, he's happy that he's now home.
