The city of light is a town above a hill, called that because it's surrounded by the sun, but it hides an obscure side. There, lives Tasuku, a young kid who works as a 'messenger' for a mysterious group who organizes suicides on the phone. At the same time other youngsters like him are trying to survive the everyday's life: Satoshi changes one occasional job after another, Momoko is the daughter of a prostitute who abandoned her. Finally there's Hoichi who is always involved in dirty business, among which is the suicidal group, but at least he has a dream: earning enough money to buy the whole place and turning it back into the country village he was born in.
