Cyclone

Local authorities issue a general alert about an approaching cyclone. Despite the warning, a small passenger plane, a tour boat, and a fishing trawler fail to receive or heed the message. The storm closes in as the vessels are caught at sea.

The fishing vessel springs a leak and sinks, forcing the fishermen to abandon ship. They struggle to stay afloat and improvise a way to survive as the ocean rages around them. The immediate danger of the sea becomes a grim daily reality.

The airplane crashes into the sea, killing most of the passengers. The few who survive cling to wreckage and then evacuate into the water to try to stay afloat. The disaster marks a desperate start for those left adrift.

The tour boat's motor is damaged by the storm, leaving the vessel vulnerable. During the chaos, one of the tourists is swept overboard and drowns, highlighting the peril faced by everyone aboard.

After the cyclone subsides, sharks are drawn to the area by the bodies in the plane wreck. They begin preying on a drifting survivor, underscoring the ongoing danger of the sea even after the storm passes.

The Mexican coast guard conducts a search that turns fruitless as days pass. After three days, they abandon hope of finding any survivors, emphasizing the severity of the situation and the scale of loss.

Plane passengers are picked up by the fishermen and later taken in by the drifting tour boat. The group swells to twenty-seven people struggling to survive on the open sea together.

With supplies dwindling, the group resorts to extreme measures, including killing a dog belonging to one of the tourists for food. Tensions rise as hunger gnaws at everyone aboard.

When one of the fishermen dies, his body is used as bait for a shark. The plan backfires as the shark snatches the corpse away, reminding the survivors of the sea's unpredictable dangers.

A second tourist perishes, and his body is butchered and cured for food by the remaining passengers. The harsh measures reflect the extreme scarcity the group faces during the ordeal.

Amid the struggle for survival, a female tourist gives birth to a baby aboard the drifting boat. The birth adds a new, fragile life to the already desperate situation.

Several of the passengers and the trawler captain launch a lifeboat to pursue outside help. The drifting flotilla is eventually picked up by a passing American yacht, initiating formal rescue efforts.

During the night, a female passenger dies and is cast overboard by her grieving husband. The loss underscores the emotional toll of the ordeal on the survivors.

The next day, a fight breaks out when Taylor attempts to hoard the remaining water. The ensuing struggle shatters the boat's glass bottom, causing the vessel to sink and leaving survivors to cling to wreckage.

Sharks continue to threaten the drifting survivors until two seaplanes arrive. The planes rescue the remaining survivors, bringing the ordeal to a conclusion with some lives saved and others lost.
