When the only hope for a six stranded scuba divers suddenly threatens certain death, the group must come together and elude their pursuers to survive a harrowing night of terror in director Pau Freixas' waterlogged action-horror hybrid. A group of scuba divers float helplessly in the cast ocean, but when a large merchant vessel comes into vision on the distant horizon they assume that they have finally found salvation. The already precarious situation quickly takes a turn for the worse, however, when the six desperate divers bear witness to a brutal execution aboard the mysterious vessel. Now, with the malevolent crew determined to silence the scared stowaways forever, the stage is set for a bloody battle of wills on the open water. ~ Jason Buchanan, Rovi
