Zeus has placed a protection order on his son Hercules so any god who kills him is doomed to spend an eternity in the abyss of Tartarus. Ares, god of war is angry that Zeus favours Hercules, so he sends his bumbling nephew Strife to trick Hercules into stealing a chalice belonging to Hera in hopes that Zeus' protection order won't extend to such an act.
In an attempt to destroy Corinth, Discord and Strife disguise themselves and bring Jason a 'gift'. The 'gift' is a baby monster that Iolaus comes to love. It soon becomes clear that the monster is dangerous.
Feeling overwhelmed with his impending role as king, Jason goes to a small village and pretends to be a travelling farm hand. He leads the villagers to face down a warlord who has been terrorising them.
Ares sends Discord and Strife to stop Jason, Hercules, and Iolaus from negotiating a peace treaty. As a result they arrive to see war officially declared. The boys come across a farmhand who looks like Ares and they train him to act like the god in an effort to convince the warring factions to agree to peace.
The cadets eagerly try to carry out the tradition of pulling pranks on seniors by trying to get Jason. Hercules discovers a plot to kill Jason and tries to get his friends to believe him and assist him in time to save Jason's life.
A new cadet named Pythagoras claims there is no scientific evidence to support the existence of the gods. Strife uses increasingly dangerous and deadly methods to get Pythagoras to admit to the existence of the gods.
Hercules' clash with the new instructor Theseus leads to them battling it out in a chariot race. The two competitors end up treading into the deadly 'Forbidden Zone' where people go in but don't come out.
The legendary Chronus Stone will give any god who possess it ultimate power. However the stone is in pieces and Zeus has made it so that gods can only possess a piece when it is freely given by a mortal. This leads Ares to enter a talent contest in which one of the prizes is the last piece of the stone he needs.
Iolaus opts not to invite his parents to the academy's Parents' Day because he believes that they will only be disappointed in him. Instead he hires actors to play them. The situation is complicated when his real parents show up.
