Mona (Sophie Simon) is the girlfriend Pierre (Denis Lavant), who is a member of a rather pathetic rock band in France. Their hero is their lead singer `Johnny Valentine`(Johnny Thunders) who, seeing that Mona is being neglected, decides to make her his own. These guys do everything to the accompaniment of music, and use lots of drugs. The story is narrated by Pierre, who is the `I` of the title.
