I'm not entirely sure specifically about the 'Open Water Adrift 2' true story. It might be about people adrift in open water, perhaps survivors of a boating accident or some sort of maritime disaster. But without more research, it's hard to say for certain.
The movie 'Open Water 2: Adrift' is based on a terrifying real - life situation. A group of friends go out on a boat, and through a series of misfortunes, they end up adrift at sea. It shows how quickly a day of fun can turn into a fight for survival. They face challenges like lack of food, water, and exposure to the elements.
Definitely not. Open Water 2: Adrift is purely fictional. The plot and characters are crafted to provide an exciting and suspenseful cinematic experience rather than being rooted in reality.
