Life changes forever when the All Saints emergency team is caught up in the unfolding chaos of a balcony collapse at a local nightclub where they are attending a New Year's Eve charity function. Emergency Department nurse Dan Goldman is the one who first suspects disaster is imminent. Risking his own life to save a young woman during the balcony collapse, he suddenly finds himself trapped alongside her in a dark room, with no one even aware they are there. Before fate takes a shocking turn at the nightclub, Dr Vincent Hughes - a man who has clearly been on a self-destructive path for some months now - enjoys a fling with yet another woman, much to the dismay of Jessica. However, Vincent is horrified when the woman is badly injured in the balcony collapse. What's more, he doesn't even know her name. Meanwhile, back at All Saints Western General Hospital, Terri - who left the nightclub moments before tragedy struck - decides she must face the music at last with both Jack, her ex-lover, and Charlotte, the woman who is carrying his baby. Realising she needs to get away from those who have turned her life upside down, Terri resolves to take leave from the hospital.
