 Bird is on a gap year straight out of school and is keen to learn everything she cam, with a special interest in the medical side of "Swain's" job, since she is hoping to become an emergency medic one day.So when Swain gets given the job of steaming home a boat load of refugees, he picks Bird to help him, unfortunately the routine voyage goes horribly wrong when they are intercepted by a gang of smugglers who murder their victims and then sell the organs on the black market.With his medical training "Swain" is forced to take over when the smuggler's own Doctor is killed, and has no choice when they threaten to kill Bird if he doesn't agree to help.
