Danish journalist Nora Sand works as a foreign correspondent in the United Kingdom. One day, she comes across a photograph of two girls who were on a ferry from Copenhagen to London in 1985 but never disembarked, and their fate remains unknown. Determined and attentive, Nora begins unraveling the mysteries surrounding this story and uncovers the trail of a man serving a life sentence. As more evidence of his guilt emerges, Nora becomes increasingly terrified, sensing that another killer is watching her. Clearly afraid of being exposed, he will stop at nothing to silence the journalist. The series "Fatal Crossing" is based on the bestselling novel of the same name by Lone Theils, published in over 20 countries.
