Dr. Eric Leonhard is an experienced emergency physician and surgeon who works on a cruise ship. A few months previously, his pregnant wife Sarah disappeared without a trace after she had tried to go to her sister’s, but never arrived. The police investigated without success.
Leonhard is convinced that his wife is still alive and that their child has since been born. So he began to investigate on his own. During the course of his research, a photo emerged showing his wife on board a cruise ship.
He does not trust the other crew members because they could be involved in the case. As a doctor who is responsible for caring for the vacationers on board, he is valued for his competence, but his aloofness causes surprise among the other crew members.
