For some people not even the apocalypse can ruin a nice day on the water.
A spring boat ride with no motor, no GPS and no radio.
What could possibly go wrong?
When Jules goes to Marseille to run an errand for the twins, she meets an exotic new friend who offers her a day trip on a French yacht to wash away the gloom of the post-apocalyptic winter Jules has just endured.
What starts out as a pleasure cruise quickly turns into the sail of the damned as, trapped on a boat with a killer, Jules scrambles to find out who not to turn her back on.
