Amidst a storm, Captain John Finnegan and his crew, Joey Pantucci and Leila, are hired by mercenaries Hanover, Mulligan, Mason, Billy, T-Ray, Mamooli, and Vivo to pilot their boat across the South China Sea to an undisclosed location in the middle of the ocean.

A large object rises from beneath and rams the vessel, leaving it dead in the water, while the panicking passengers are attacked by unseen creatures.
