When toy robot, Boot, wakes up at a scrapyard, it has no idea how it got there and why it isn't with its owner, Beth. It only has two and a half glitchy memories, but it knows it was loved, which means something important to humans.

Boot soon realises its emotions make it different to other robots, who just function and don't think. Boot is scared but tries to be brave, which is hard when its screen keeps showing a wobbly, worried face. Luckily Boot meets Noke and Red - other 'advanced' robots who have learned to survive in secret.

With new friends by its side, Boot is determined to find Beth and the gang set off on a dangerous adventure. Everything Boot thought it knew about the world is changing, and things aren't as simple as it remembers . .
