Jack is now engaged to Jayne but overreacts when new nurse Tina Seabrook makes an unfortunate comment about a man who deliberately fell off a ladder to get into hospital. Josh and Liz try to get Ian and Esme, a couple who are having a baby to the hospital, but end up having to deliver the baby in the back of an ambulance. Young black couple Jason and Lou are arguing about her desire to join the police, who Jason sees as institutionally racist. After they part ways, Jason sees someone park a van in the car park at a shopping centre. A bomb in the van goes off, causing many casualties. An elderly man removes glass imbedded in his wife's stomach and she dies of internal bleeding. Lou seems to have minor injuries but in hospital a scan shows she has a bleed on the brain, which leaves her in a coma. Ian has been left trapped in rubble and when a second bomb is discovered Baz and Josh amputate his foot to get him out.
