Growing out of the chaos of a global war, the city of Utopia is populated by humans and bioroids (artificial humans). On the surface, everything is harmonious, but tensions lurk. Into this seemingly perfect society comes a survivor of the wars, Deunan Knute, who carries a legacy that will turn out to be of critical importance to the future of humanity.

Set in a different series of events, this story does not follow the previous Appleseed movie canon (despite being directed by the same director of the previous movies); it is an alternate story to their beginnings. Briareos is already a cyborg and did not become separated from Deunan to be later reunited in Olympus to join ESWAT.

Appleseed Alpha depicts the early days of Deunan Knute and Briareos in the 22nd century, as they embark on a journey throughout dystopic ruins of New York in search of the city of Olympus. They are hired by Two Horns, the warlord of the ruined city, to eliminate bipedal combat machines. During the fight, they encounter Iris and Olson, both on a mission. Deunan and Briareos befriend them and decide to join their mission.

Iris is tasked with preventing the malevolent cyborg Talos from capturing a secret weapon humans were building. Talos uses Iris to activate the gigantic war machine.

This is a remix, theatrical release of the first half of the Appleseed XIII series.

In the wake of the destruction of a worldwide non-nuclear war, the city Olympus has become the control center of the world. Run by Bioroids (cloned humans made from only the best DNA), it is defended from terrorists by special military forces. Among these are former LAPD SWAT member Deunan Knute and her multipurpose cyborg partner Briareos. They face a challenge from the Human Liberation Front and its terrorist underbelly the Argonauts. The leader of this group, Al Ceides, supposedly died 20 years ago in an attack on Poseidon, but now his shadow emerges once again.
