Ed and Lin face off against Envy, and Ed finds himself hesitating to attack due to all the people embedded into Envy's body and gets swallowed. Meanwhile, Scar and May find Shao May with Al and Gluttony and decide to follow them down to an underground tunnel, fighting off several chimeras. Ed spots the Philosopher's Stone inside Envy and manages to figure out a way to escape from Gluttony after seeing the missing piece from the ruins of Xerxes. Bradley explains to Roy how he was trained from birth for leadership and was injected with the Philosopher's Stone. Using various pieces of the Xerxes ruins found in Gluttony's stomach, Ed reluctantly uses the souls inside Envy's stone to transmute himself and open the Door of Truth to escape through. Ed finds Al's body but is unable to bring it back since it isn't his. However, before the Door closes, he bursts through yelling to Al's body that he will come back to get him someday.
Edward and Alphonse Elric's reckless disregard for alchemy's funandshy;damental laws ripped half of Ed's limbs from his body and left Al's soul clinging to a cold suit of armor. To restore what was lost, the brothers scour a war-torn land for the Philosopher's Stoandshy;ne, a fabled relic which grants the ability to perform alchemy in impossible ways.
The Elrics are not alone in their search; the corrupt State Military is also eager to harness the artifact's power. So too are the strange Homunculi and their shadowy creator. The mythical gem lures exotic alchemists from distant kingdoms, scarring some deeply enough to inspire cuddle. As the Elrics find their course altered by these enemies and allies, their purpose remains unchanged - and their bond unbreakable.
