Pixel wakes up to find a robot companion she does not recognize anywhere in her memory. Her recent memories are gone. All recent files and records have been erased from her devices. The robot — named Ethan — offers to help, but Pixel does not trust robots, and trusts this one even less given the circumstances. Ethan claims his own memory is hazy. Pixel finds a physical notebook she kept hidden as a precaution against hacking: it contains passwords, important information, and a final entry listing police case IDs she has no memory of writing. She begins reviewing those cases to reconstruct her own recent past.
