They made a lots of crime movies like this in the 60's. The script (if there is any) hasn't given much thought and is full of holes. The characters are empty and stupid, there are always drugs involved and at least one party scene full of grass smoking messed up hippies. Jane Birkin and Serge Gainsbourg spend most of the time kissing and touching each other while the other "gangster" is just fooling around. From time to time, police is trying to catch them with zero results. Acting is bad and the dialog is ridiculous. However, there are still some nice shots in it and the soundtrack (composed by Gainsbourg) is fantastic and that is a reason enough to check out this piece of crap.
