The Dive (2023) Timeline Explained – Every Event in Order

May's distance stems from traumatic childhood memories of her father forcing her through harsh underwater breathing exercises to push her beyond her limits. This past abuse created her fear of deep water and explains why she remains emotionally withdrawn throughout the dive. Drew's attempts to connect are met with resistance because May has never processed this trauma or shared it with her sister.

Foreshadowing: Early scenes show May avoiding Drew's attempts at conversation and remaining quiet during the car ride, hinting at unresolved emotional pain.

While the sisters are exploring a deep underwater cave, a landslide occurs from the mountainside above, sending rocks crashing into the ocean. May becomes trapped beneath the debris in a narrow tunnel, pinned by large boulders with rapidly dwindling oxygen. Drew's torch reveals near-zero visibility as sand and debris cloud the water.

After May becomes trapped, she and Drew agree on a 20-minute window for Drew to surface, retrieve extra oxygen cylinders and a car jack from the car, and return to help lift the rock. This time constraint represents the amount of breathable air May has left in her tank, creating a desperate race against time and suffocation.

Drew surfaces and finds the spare cylinders trapped beneath the collapsed rocks, inaccessible from the surface. She climbs to the cliff, smashes the car window with a rock, and attempts to access the trunk. When the trunk jams, she slices open the backseat with a knife but still cannot reach it. She eventually retrieves one cylinder and spots a nearby boat, forcing her to improvise.

May recalls her father putting her through brutal underwater breathing exercises as a child, forcing her to dive beyond her limits in a disciplinarian manner. This explains her deep-seated fear of underwater environments and her emotional withdrawal from her sister. The trauma has shaped her relationship with diving and her inability to connect with Drew.

Foreshadowing: May's reluctance to discuss her feelings about diving and her short, pointed responses throughout the dive hint at this painful past.

Drew attempts to use her inflatable BCD (Buoyancy Control Device) jacket as a makeshift airlift beneath the rock pinning May. The idea is to inflate the jacket to lift the boulder. However, the jacket's safety valve releases a burst of air, complicating their efforts. Drew then returns to the surface to find a more effective solution using spray foam to seal the valve and fill the jacket properly.

After Drew exhausts herself free-diving to retrieve the last usable cylinder, she becomes unconscious and stops breathing. May quickly performs CPR on her sister, reviving her. This moment marks the culmination of their reconciliation, where May's survival instincts and medical knowledge save Drew's life.

May locates a filled oxygen cylinder in the cave and positions it between two rocks. She breaks the cylinder's valve to flood the small breathing chamber with fresh oxygen, creating enough air to revive Drew after her CPR. This improvised solution provides the critical oxygen boost they need to survive.

Foreshadowing: Earlier in the dive, the sisters discover this small chamber where they can briefly breathe without masks, establishing it as a key location.

Drew heads to a church she spotted on land, hoping to find tools that could help with the rescue. She breaks in searching for anything useful for a car issue or lifting the rock. Finding only a hammer, she returns to the car with the intent to smash the trunk open. She also leaves an SOS mark on a map in hopes of drawing attention from anyone who might see it.

When Drew descends with one cylinder, it slips away from her and sinks to the bottom of the cave, becoming unreachable during her limited air supply. This forces her to free-dive without proper equipment to retrieve it, putting herself at greater risk but providing the crucial oxygen needed for both sisters to survive.

After reviving Drew with CPR and flooding the breathing chamber with fresh oxygen from the cylinder, the sisters make a desperate free-dive back to the surface. Both are exhausted and low on air, but they manage to reach the surface together. They emerge at the diving platform and collapse into each other's arms, embracing in a hard-won moment of healing and reconciliation.

May notices that Drew's oxygen pipe is leaking, adding another layer of danger to their already precarious situation. The leak reduces the amount of breathable air available and increases the urgency of their escape. May warns Drew about the leaking pipe, underscoring the gravity of their situation as they work to survive.
