Breaking Down the Surprisingly Emotional Ending of Shark Thriller The Devil’s Mouth

Before Max’s death, Sara and Max discover an opening that could lead outside the cave. However, they realize the drop is too high to escape safely. Their plan is to wait for the tide to rise, allowing them to jump safely into the ocean from the opening without risking a dangerous fall.

After Max dies, Sara is alone inside the cave. She uses the flare she was carrying to distract the shark and force it away. With it still following her, Sara creates a trap using the unstable rocks inside the cave. She draws the shark toward her and causes it to repeatedly crash into the rocks, until they eventually collapse and crush the shark.

After defeating the shark, Sara searches for another way out of the cave. She finds a second opening in the cave system and climbs through it, emerging near the beach, with trees and sand surrounding the area. Unlike the previous opening that led out toward the ocean, this exit allows Sara to reach land and finally escape the Devil’s Mouth alive.

Reflecting on Sara’s transformation, Newton says portraying her growth required embracing the character’s initial insecurity and her reliance on Max as a source of confidence. “I didn’t like that Sara was such a baby and had to lean into it to discover her strength,” she says. She also highlights the importance of Sara and Max’s complicated friendship, explaining that Wadlow was drawn to “how they have to really turn against each other to find each other.”

By the end of the film, Sara becomes the one making the decisions and taking control of her own survival. “Once I became the apex predator that a teenage girl is, I couldn’t be stopped,” Newton adds.
