The underground wanderings of a not-so-young Brazilian student who, without knowing what to look for in life, goes to the Paris subway to meet those he values most... the strangers. During two years, always with a camera on him, he observed and interacted with all kinds of metro 'inhabitants': passengers, bill posters, homeless persons, musicians, metro drivers, frequently conversing about life expectations. The result is a film that reveals this eclectic underground world from an unusual, irreverent and personal point of view.
