Set in 480 BC, the cruel and merciless King Xerxes (David Farrar), leads his two-hundred thousand strong Persian army towards Greece, with hopes of invading and conquering the nation in its entirety. The brave and determined Spartan army, led by King Leonidas (Richard Egan), battle against these forces at the narrow pass of Thermopylae, in an attempt to free the country of Greece. An importantly historic tale that is worth a watch, but somewhat underwhelming in stages.
