Extensively drug-resistant tuberculosis, known as XDR-TB, has become one of the deadliest health threats in South Africa, a strain that shrugs off the standard drug regimen and keeps mutating past it. At Jose Pearson Hospital in Port Elizabeth, the film follows Zelda Hansen, a young mother diagnosed with the disease who feels well enough to walk out the door but cannot, because she is still contagious enough to endanger her husband and children. She describes the isolation ward as a kind of imprisonment for a crime she never committed, and the camera stays with her through the waiting, the treatment, and the separation from her family rather than cutting away to statistics. Doctors and nurses at the hospital explain what makes XDR-TB harder to treat than ordinary TB and what containment actually costs a patient day to day. Zelda's case stands in for a much larger caseload moving through the same wards, and the film uses her routine to show what an epidemic looks like at the scale of one family.
