Justice that's hardly true.
While the writers (and I dont' say this jokingly) were obviously on MAAAAANY drugs (when I did the show my director was tripping on acid, pot, alcohol and something else when the sun started to rise and he finally felt at that moment he truly understood Hair - see what I mean?) when they wrote it and it takes a lot of tweaking and cutting to make sense of it, there is a semblance of a plot and storyline.
It is, as you said though, mainly inside looks into the relationships the kids on "teenybop island" share and their acts against the war.
It mainly follows Claude in his journey from being against the war to receiving his draft notice and being too much of a chicken to fully stand up and refuse to go, to burn his draft card, to think of something that will basically make him ineligible to be drafted...to the point that in the end he ends up going because he's too afraid to really fight it and he ends up dying in Vietnam.
Besides that it's about the love triangles/squares/octagons, etc. - Jeanie (did I spell that right?) is in love with Claude who is in love with Sheila who is in love with Burger who's in love with himself basically. There are hints that Wolf may have a thing for claude but I honest don't remember if that was a director's choice we did or if it's really written in...
There are vignettes showing their lives outside of this colony of hippies - how they relate to their parents, their teachers and other authority figures, etc.
It's not a terribly intricate and clear storyline/plot - but if the show's done right, it's pushed to the forefront and makes the show that much more powerful.
Hope that helps.
Prolly not.
Drop some acid then try to figure it out, lol.
If I show you the darkness I hold inside, will you bring me to light?
