Ok, I started off with a nice little semi- synopsis/explanation, but then I deleted it on accident and I'm lazy and won't type it out again. So here's a cheat sheet.
Mark(filmaker, the narrator of the show)- Straight, HIV negative, used to date Maureen, best friends with Roger.
Roger (ex-junkie guitarist, trying to write one great song before the virus kills him)- Straight, HIV positive, last girlfriend killed herself and gave him HIV before the show starts
Benny (owner of the soon-to-be CyberArts)- Straight, HIV negative, used to date Mimi, Mark and Roger's former roomate until he married a yuppie girl and bought the building that he used ot live in with his friends and the lot next door where he plans to build an internet company.
Mimi- (S&M dancer)- Straight, HIV positive, was with Benny but now is interested in Roger, though she doesn't know they know each other at first
Collins (Computer genius, teacher and vagabond anarchist who once ran naked through the parthenon)- Gay, HIV positive, friends and former roomate of Mark and Roger
Angel (drag queen and street drummer)- GAy, HIV positive meets Collins and his friends at the beggining of the show, falls in love with Collins.
Maureen (performance artist, the dramam queen)- Gay, HIV negative, dumped Mark for Joanne before the show, protesting Benny's company
Joanne (lawyer)- Gay, HIV negaitve, dating Maureen, and other stuff I don't feel like typing
So that's the basics. Any questions? There will be a quiz on this.
