I first noticed this show around episode 20 in series 1 and having the DVD it shows what is a possibilty if a Virus wiped out the entire adult population. In Series 1 it shows a group of children forming their own tribe and that they want to create a better world different to the current one in hich tribes fight for food, territory and slaves. However after Series 2 it begins to go slightly downhill because in Series 1 it is dangerous to walk outdoors by yourself and the fear of larger warlike tribes (e.g. Locos, Demon Dogs) attacking you. Now it is safe to walk down the street and everyone gets along but series 3, 4 and 5 have the same basic storyline of a large tribe taking over the whole city.
However this is worth a watch and shows many different characters which have their own personalities and dreams.
