When Scar is cornered by a pair of gruesome chimeras, the Elrics enter the fray as his unlikely allies. Later, Winry's attempt to confront Scar over his role in her parent's death ends in disaster.

The ruse of Winry's abduction by Scar is revealed, but a plan of rescue must still be hatched. A brutal storm is coming - one which only Alphonse Elric can brave.

Bound by more than blood, the Elrics have long shared joy and pain. Now, with Al wandering the frigid void - and Ed losing blood by Kimblee's hand - the mystical connection of their souls could prove fatal.

May and Marcoh's efforts to decode the research of Scar's brother yield progress, but it might be too late to prevent catastrophe. Violence is spreading across the land, and it will soon reach the northern border.

In the snowy north, the soldiers of Fort Briggs engage an invading army, and Marcoh leads an attack against monstrous Envy. In Central, an ominous and shocking secret is revealed to Olivier Armstrong.

Hohenheim and Alphonse enjoy a chance to get reacquainted. Their bond is restored with ease, inspiring the father to share his secrets with his sons - but one of them is far away and on the run.

Those who have prepared to reclaim a nation find their plans exposed. The chaos multiplies after an assassin strikes down a mighty leader in broad daylight, and Alphonse falls prey to monsters in the dark.

With his father's help, Al takes incredible steps to contain the monstrous Pride. As the sun begins to rise on the Promised Day, the youngest Elric listens while the Homunculus ponders his very human mother.

Mustang leads a ragtag assault force of hardy northern troops - and welcome faces from the past - against Central's defenses. Victory seems certain until the military's most horrifying secret is revealed.

Ed's crew faces a horde of ravenous mannequins, abominations powered by human souls. The twisted creatures aren't the only unstoppable force on the battlefield -Pride, Sloth, and Envy are on the move.

With a Philosopher's Stone in his possession, Alphonse fearlessly engages Pride and Kimblee. Elsewhere, the Armstrongs find themselves trapped between Sloth's onslaught and the guns of Central's troops.

After a startling radio broadcast grants Mustang's forces the advantage over Central's troops, the Flame Alchemist unleashes the brutal power of burning hatred in the battle against the killer of Maes Hughes.

As the light of the sun vanishes, Mustang learns the loss which comes from seeing the other side of the Gateway - and five sacrifices gather in the dark presence of the Father.

A truly epic battle erupts when Edward, Mustang, Hawkeye, Greed, Izumi, and Armstrong attack the god-like Father. The odds are against the forces of good - until one brave boy makes a shocking sacrifice.

When the battle ends, the one known as Father meets his final fate beyond the Gateway. When the one known as Fullmetal enters the sacred space, he finds only the promise of a new beginning.

As one shared journey ends, many journeys begin. Those most touched by the conflict which surrounded the Philosopher's Stone now go their separate ways. One thing is certain: they will meet again.
