1. Against All Odds (2008)

The train on which Marian was travelling crashes, trapping her in the wreckage. Although she cannot escape, she's free to move around the carriage to help those injured, assisted by fellow passenger Dr Nick Burnett - who turns out to be the Royal's new locum. Back at the hospital, a shortage of staff puts the casualty department under pressure when the crash victims begin to arrive.
