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, Rovi
