Open Water (2003)

Open Water is based on a terrible true story. Daniel and Susan (Blanchard Ryan) are enjoying a dream tropical vacation when they decide to go on a diving excursion. After seeing the wonders of the seabed, the two emerge and discover that they have been left alone. The boat has gone, forgetting them. The couple find themselves floating in the middle of the ocean, surrounded only by water. And sharks, at one point.
At the seventh minute, Blanchard Ryan is lying on the bed totally naked, with her back against the headboard and a magazine in her hand. She is tanned and beautiful, with white cream on her face to soothe sunburn. When a man lies down next to her, Blanchard puts down the magazine and turns to him.
