47 Meters Down: Uncaged (2019), directed by Johannes Roberts, is a shark-driven survival horror film centered on a group of young women trapped inside a submerged cave system. As visibility disappears and oxygen runs out, great white sharks turn the underwater ruins into a lethal environment. The film continues the concept of the original 47 Meters Down, focusing on claustrophobia, isolation, and predator-based terror rather than adventure or exploration.
