Dawn of the ED - Part One is the 687th episode of Casualty and the 1st episode of the 24th series.
Synopsis
Adam Trueman begins his first day as Clinical Lead of the ED by greeting the eight new F2 doctors, including Heather Whitefield, May Phelps, Yuki Reid and Lenny Lyons. Adam and Heather attend a call-out to a deserted shopping centre, where one patient is trapped in an industrial fan, another has fallen from a balcony, and numerous homeless people are living in the basement. Unaware that the centre is occupied, its owner rigs the building with explosives as part of an insurance scam, detonating it with dozens of people trapped inside.
