The first twenty minutes or so of the film is explicitly erotic, setting the stage for the remainder of the film -- The story is simple -- While in heat, they have unprotected sex -- One partner is HIV+ (although with a low viral load) -- the other panics and seeks immediate medical assistance -- During this time they get to know each other and discover, at least for the moment, that they may have a continuing affection for each other in spite of the circumstances -- the action more or less takes place in real time, hence the 05:59 in the title is the actual time at the end of the film (of course the action takes place over several hours, but the film is only 1½ hours long) -- In summary, I found the film to be a nice little snapshot story worth seeing, but not likely to be one of the enduring greats.
