The cybernetic organism known as 812-3 is in prison, convicted of murdering a human worker but he claims that he did not do it. With the evidence stacked against him, his lawyer, Aiya Ritsehrer, must determine grounds for an appeal and uncover the true facts of the case. But with artificial life-forms having only recently been awarded legal rights on Earth, the military complex on Europa is resistant to the implementation of these same rights on the Jovian moon. Aiya must battle against her own prejudices and that of her new paymasters, to secure a fair trial for her charge, while navigating her own interpersonal drama, before it's too late.
