Holby City's A&E department race to the scene of a major train accident.
Consultant Mike Barratt and Staff Nurse Lisa Duffin swing into action in events which are every bit as dramatic as the fire which ended the last series. A stolen car stalls on a level crossing and causes a horrific rail crash and the battle is on to save people trapped in the train. Back at Holby, Charlie is annoyed with Mark over staff problems and Ash fails to get his promotion, losing out to Ken. Josh clashes with Dr Karen Goodliffe, as he tries to do his job.
