The year is 2034, the fictional French city of Belleville. As a result of successful reforms of the mayor's office, the government has built an ideal city to live in. The entire city center has been turned into bicycle paths, only vital traffic is left in the city center, and work is underway to green the city. The main street is the Jeanne D'Arc Street. All the necessary places are within a 15-minute walk from the house. No houses are alike, everyone tries to be different.
