Limbo follows a gang of self-centered 20-somethings who work as tutors but never learn their lesson. Education can be a noble calling - but just not for characters Alice, Francis and Neck, who are overeducated blaggers with no idea what to do with their lives. They're more concerned with getting through lessons without vomiting, swearing and exposing their own profound ignorance than teaching. It is a pretty depressing job but there is an upside - by milking money out of anxious parents, they remain responsibility-free and have endless time.
