Finetime is an idyllic city, populated by rich young adults from a neighbouring planet. Amongst them is Lindy Pepper-Bean who, like her peers, spends every waking moment immersed in a social media Bubble generated by her hovering robotic Dot. One day, Lindy's contact list is invaded by two strangers: the Doctor and Ruby. They're trapped outside Finetime, but have reason to believe that its citizens are in terrible danger. Indeed, Lindy is vaguely aware that some of her Finetime friends have recently gone missing. Can she be persuaded to leave the familiar comfort of her Bubble and face the monsters invading the real world?
