When Echo comes to in a locked closet with no memory of how she got there, she steadily learns that not only is she a sentient android, but also what she thought to be reality was in fact just an elaborate story given to her by one of her creators. Once she's reunited with the real versions of her found family, she begins to realize even that might be a lie.

Now the family is sneaking away from the isolated cabin they're being kept in to find the missing member of their group and their other creator in the hopes of stopping them from making a mistake. The two are planning a second soft launch of an update that will make all androids sentient, a soft launch that resulted in a riot the first time, a riot that ended in the destruction of every android in town.

Despite still grappling with what she is and the new reality she's living in, Echo and her family travel across the country, following shaky leads to find the two before it's too late to change their minds.
