Coming in on the heels of his internationally acclaimed first film, Le Dernier Combat, 26-year-old director Luc Besson created this tongue-in-cheek look at filmmaking and at the denizens in the tunnels of the Paris Metro -- a new kind of underground movie.
Fred (Christopher Lambert) has just stolen some major documents from a birthday celebration given by the Paris elite for one of their kind, Helena (Isabelle Adjani). He takes off into the Metro just as it is shut down for the remaining few hours of predawn darkness and once in the Metro encounters several characters in the tunnels.
There is a bodybuilder who works out with subway parts, a purse-snatcher, and a flower seller of dubious ethics. Inspired by the moment, Fred decides to recruit a few of the ubiquitous musicians who perform (some of the best music around) on the Metro's byways, and he creates a rock band.
Through all of these encounters and activities, the police and others -- including Helena -- are after Fred for their own reasons, none of which coincide. As Fred discovers, going underground can be risky.
