An unexpected story of life, family, hope, and redemption–at the end of the world (maybe). Arto wakes up in a desolate world devoid of humanity–he’s a robot, he knows that much–but he has no memory of how he got here. With a mysterious letter and a cheeky kitten as his only companion, he embarks on a quest to understand his existence. As Arto navigates this unfamiliar landscape, he stumbles upon a cantankerous robot who claims to be his sister. And that’s a problem, because she might be the reason there are no more people.
