The score of this movie is the techno at a San Francisco underground dance party—the site of one ecstatic night in the lives of several iconic characters. The traditional ensemble narrative—a new romance begins, an old one gets complicated, friendships and values are tested—is divided into sections bracketed by the arrival of each new DJ and is enlivened by the edgy yet trendy environment. Writer-director Greg Harrison's sweet parable mixes melodrama and ethnography in arguing the irrefutable: that a subculture organized around the use of illegal drugs isn't so different from a culture organized around the use of legal ones. With Lola Glaudini, Rachel True, Hamish Linklater, Denny Kirkwood, Steve Van Wormer, and Mackenzie Firgens. 86 min.
