The film is about a group of hijackers who hijacked the world's most expensive cruise ship. Now, these people are shocked to discover passengers who mysteriously disappeared. In those moments, everyone begins a battle with a series of large-scale dirt-shaped marine creatures who seized the ships at that moment.
The rest of the movie is a predictable guns 'n' beasts gorefest that wants to be equal parts Aliens, Titanic, and Anaconda but winds up being all parts crap.
