The Nereus is a fifty-year-old Ice Breaker, salvaged by an idealistic crew on a mission to catch unlawful fisherman. On chase, the crew discover themselves properly off-course and bearing down on a physique mysteriously floating in the midst of the Satan’s Sea. Superstitious or not, the staff quickly discovers they’ve rescued a lethal creature feeding on the lifeless physique. Their new mission—kill or be killed and ideally earlier than they hit land.
