Xena: Warrior Princess

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.
