Hoping to learn more about the Homunculi, Ed and Al devise a risky strategy to lure the creatures out of hiding. Step one of the brothers' plan: risk death at the hands of their most dangerous enemy - Scar.

Scar's mission to destroy those who slaughtered his people is fueled by justifiable rage. Upon learning the role Scar played in her parents' deaths, Winry claims those murderous feelings as her own.

Cooperation between Mustang's cabal and Ling Yao's band leads to the capture of a Homunculus. Unfortunately, their actions also capture the eye of the Homunculus hiding atop the military's ranks.

Gluttony's twisted powers overwhelm the Elrics - and the creature's appetite is satisfied by battle's end. Meanwhile, Mustang acts on his suspicions of Bradley and finds himself in the belly of the beast.

The Homunculi are winning. Ed and Ling face a horrific enemy within the hellish expanse of Gluttony's gut. In Central, Mustang can only watch as his loyal band of soldiers is divided by Bradley.

Truths are exposed when Al finds the one called Father, and Mustang hears the tale of Bradley's creation - but the most amazing revelation is reserved for Ed after he once again breaks alchemy's greatest taboo.

Visions of the past play out by a warming fire as Hohenheim reflects on the unavoidable follies of man: the pain that comes with a loving family; the hidden truths of alchemy; and the roots and results of war.

The Elrics come face to face with Father - and his face is familiar indeed. Powerless and amazed, Ed and Al can only watch as Father creates a new Homunculus with alchemy that should be impossible.

The Elrics are at Bradley's mercy; if the brothers make one wrong move, those dearest to them will pay. As Mustang quietly gathers allies at his side, Ed discovers there may be no need to find a Philosopher's Stone.

As Edward hears Hawkeye's tale of a time when idealistic young soldiers were tasked with genocide, the horrors of the Ishvalan battlefield are revealed.
