AIDS Inc. examines the business built around a diagnosis, tracing where AIDS research funding, drug royalties, and testing revenue actually go. The film interviews scientists, doctors, and activists who argue that the pharmaceutical and testing industries have financial incentives to keep the accepted narrative about HIV and AIDS unquestioned, and it revisits the original virus-isolation studies that the mainstream account rests on. Interview subjects include researchers who challenge the safety and efficacy of antiretroviral drugs like AZT, along with patients who describe their experiences with diagnosis and treatment. The film also looks at how AIDS charities and awareness campaigns raise and spend money, and how skepticism toward the official consensus has been treated by regulators and the press. It does not pretend to settle the underlying science; instead it lays out the financial architecture around the disease and asks viewers to weigh who benefits from which version of the story being believed.
