Now, ten years later, the Greeks realize they will never take Troy without Philoktetes and the bow given to him by Herakles. But Philoktetes refuses to rejoin the Greek army, vowing to kill his enemy Odysseus instead so Neoptolemos, son of the slain hero Achilles, is dispatched to trick Philoktetes into returning.

This is Sophocles for a new generation, certain to strike a powerful chord with contemporary audiences everywhere.
