The Shallows unfolds the story of a young woman named Mia, played by Blake Lively, who finds herself stranded alone on a rock about 20km offshore. The trailer opens with breathtaking shots of the vast ocean, its fierce waves crashing relentlessly and powerfully. In the midst of the expansive nature, the sight of a injured girl standing out makes viewers even more curious, raising hundreds of question marks. The curiosity heightens as the second character appears - the great white shark, a haunting predator lurking in the deep sea, now present in the shallow waters.
