Magali is a young woman of 27 years old. She has always lived in Froncles, a french village, and never visited even the rest of her own country. With her husband Olivier, they are used to play radio quizzes or games of chance. One day, she turned the radio on, picked up her phone, answered somehow the questions and won the trip of her life: in few days, she will take a train for the first time of her life to board on one of the most beautiful ship ever built, Queen Mary 2^nd. She and her husband will be introduced in a world of which they ignore the codes and that they'll never see again.
