When Yang — a lifelike, artificially intelligent android that Jake and Kyra buy as a companion for their adopted daughter — abruptly stops functioning, Jake just wants him repaired quickly and cheaply. But having purchased Yang “certified refurbished” from a now-defunct store, he’s led first to a conspiracy theorist technician and then a technology museum curator, who discovers that Yang was actually recording memories. Jake’s quest eventually becomes one of existential introspection and contemplating his own life, as it passes him by.
