The titular sword in this episode is well named: Anyone who holds the weapon is incapable of telling a lie. Hoping to prove that warrior-turned-pacifist Amphion (Brad Carpenter) is innocent of murder, Hercules (
Kevin Sorbo) and Iolaus (Michael Hurst) search for the sword in the grim Thalian caves. They are guided in this endeavor by Amphion's virginal sweetheart Leah (Kim Michalis) -- while the real murderer, not wishing to be forced into a confession by the sword, plots the demise of the three intrepid do-gooders. ~ Hal Erickson, All Movie Guide
