Arcadia follows the story of a mysterious young woman. After being struck by a car, her body is brought back to life by a brooding figure that goes by the name "Stanley." He offers her the chance of a lifetime - to have her life restored and enhanced with unique and wonderful powers that would make her nearly invincible. No longer would she be human, but something Stanley calls a "Moxie." But like most offers, there is a price to pay. She must work as his underling and kill the other moxies he has restored, or she will be killed herself. Arcadia learns to harness her powers and become the greatest moxie she can be.
