Having crossed the mountains to Mordor, Frodo and Sam wear the garments of Orcs in order to pass unnoticed by unfriendly eyes. Small as they are, with their guises pulled tight about them and large helmets upon their heads, the Hobbits make passable Orcs. Even so, the journey is perilous. With Frodo's health failing and his mind under siege, Sam sets his will to the task of protecting Frodo and encouraging him as they draw ever closer to their ultimate distination and the grim fulfillment of the quest.
