Xena, a fierce female warlord is determined to take control of the region of Arcadia. She realizes the only way to do this is to kill Hercules, because no army would dare stand up to her if she had the head of the legendary hero. She seduces Iolaus and gets him to join her under the guise of a freedom fighter. She then convinces Iolaus that Hercules does not think Iolaus can handle this by himself and convinces him to fight Hercules to the death.
Xena is back, and her men are losing faith in her after she spares the life of a child when they slaughter a village. Her lieutenant, Darphus, convinces the men to turn on her, and Xena is forced to face the gauntlet, an ancient ritual in which a member of an army is forced to walk through a line of all the men, and if she survives the beating, she is allowed to go. In order to get her men back she decides to kill Hercules and regain their respect but fails and joins Hercules in fighting her men and takes her revenge on Darphus.
Ares decides to bring Darphus back from the dead and gives him Graegus, his demonic dog. When Hercules and Xena find out about him being alive they set out on a mission to kill him again. Along the way they meet up with Iolaus. Iolaus does not trust Xena because of what she put them through in the past. After finally earning his trust by saving his life, all of them go to hunt down Darphus and kill in a way that will make sure he stays dead.
