All I remember is that the opening of the movie was of a woman swimming in a reef. She is wearing a slightly see through white top and has only a face piece on. (Maybe no face piece?) no other equipment. The scene ends with her getting onto a small boat.
Into The Blue (2005)?
Thank you for the comment! After much searching I found it and it wasn’t anything like I remembered. Kinda crazy how memory works. Lol it’s from “the deep” with Jacqueline Bisset.
Solved!
Glad you found it and thanks for letting us know!
