Father Sherko is increasingly concerned that his daughter Resa is getting sick. Presenting themselves at the hospital they encounter a number of asylum seekers from their block, all demonstrating similar symptoms. At first it looks like an epidemic of flu, but soon it appears to be something infinitely more sinister. Quickly the civil and emergency services are beyond breaking point and it emerges that the authorities are powerless to halt this disaster. When Asylum Support Unit worker Rabeena Dhondy arrives at Sherko and Resa's flat she finds the little girl is suffering from an extremely bad cough. At the hospital, the doctor Annie Millbrook diagnoses flu.
