An aging hipster encounters his misspent youth (1968 to be exact) 20 years after the misspending. By 1988, the post-Reagan "roll back the clock" cultural mindset is well-established and our hero suffers from career disappointments, divorce and the onset of drug abuse.
The plot naturally includes sex, drugs; rock and roll -- even some violence during a Paris riot -- but there is a spiritual subtext throughout: is there any actual power in goodness? The angelic female lead works strange "miracles." Why can't I?
