In the mid-1970s, children in and around Lyme, Connecticut, began developing a strange cluster of arthritic symptoms, and doctors eventually traced the cause to a tick-borne bacterium. Decades later, this film argues the disease never got contained. It follows patients like Mandy, a nurse who becomes bedridden despite years of antibiotics, and Elizabeth, whose case pits her family against skeptical doctors, as they search for physicians willing to treat lingering, hard-to-diagnose infections. On the other side are the researchers and medical boards who maintain that chronic Lyme disease is not a real diagnosis, and the film shows doctors who prescribe long-term antibiotic treatment facing formal complaints and license investigations for doing so. Interviews with microbiologists, patients, and the so-called "Lyme-literate" physicians lay out how a tick bite becomes a fight over medical authority, insurance coverage, and what counts as legitimate evidence. The film treats the science as contested rather than settled, and leaves the viewer with an epidemic that keeps spreading faster than the medical consensus around it.
