The title of Jay Corcoran’s documentary refers to the stage in AIDS treatment in which the virus is undetectable in the patient. But it also refers to the status of the disease itself in the general consciousness. It’s been beaten, right? Now all we have to worry about are anthrax and smallpox.

Not quite. Over a period from 1997 to the present, Corcoran recorded the lives of six Boston-area AIDS sufferers, a cross-section of classes, races, genders, and sexual preferences ranging from mandarin talk-show host David Brudnoy, who nearly died from the disease in 1994, to Matilde Garcia, a recovering heroin addict living in a housing project whose fifth child was born HIV positive. Each undergoes, with varying degrees of success, treatment with the "AIDS cocktail," a multi-drug regimen that has proven effective in stemming the plague. But not curing it, and in some cases the treatment causes symptoms that are worse than the disease. Corcoran cuts with sometimes distracting speed from one subject to the next, a technique that reaches dizzying heights in a clipped montage where all six appear in Brudnoy’s apartment for his radio show. Nonetheless the pain, spirit, and urgency come through in this reminder that AIDS and its victims are still with us even if "undetectable."
