What is the plot?

Kaya Adams sets out on what should be a carefree jet ski trip from Florida to The Bahamas with her best friend Tessa Miles and two acquaintances, Julian and Xander, but the day collapses almost immediately into disaster when the group's machines collide and the fun, sunlit excursion turns fatal. Julian dies in the crash, Xander is left severely injured, and Kaya and Tessa are forced into the open water with no real protection, no meaningful help, and the awful knowledge that one of their friends is already gone.

The sea around them feels huge and indifferent, a bright, empty expanse that offers no comfort as they drift and struggle to stay afloat. The shock of the accident hangs over Kaya and Tessa in waves: first panic, then numbness, then the hard, quiet effort of survival. Xander's condition makes every minute worse, because it is clear he cannot simply wait for rescue forever. Just when their situation seems at its most hopeless, a fishing trawler appears and Captain Rey takes them aboard, presenting himself as a rescuer when, in fact, he is anything but.

At first, the trawler feels like salvation. The deck is real, the lights are steady, and for a few brief moments the survivors can believe they have escaped the sea's cruelty. But the mood aboard the ship changes quickly. The hospitality is thin and unnatural, the crew's behavior unsettling, and the vessel itself seems to breathe secrecy. Kaya begins to sense that something is very wrong long before the truth is spoken aloud. The captain's calm authority becomes menacing, and the seemingly helpful rescue turns into a trap.

That trap is revealed to be a black-market organ trafficking operation run by Captain Rey and Dr. Curtis Hunt. The ship is not rescuing desperate people out of mercy; it is harvesting them for profit. The revelation turns every earlier gesture of kindness into a lie. Xander, whose injuries make him the easiest target, becomes the first victim. His organs are harvested for the black market, and his death is the film's first murder on the ship, directly caused by Captain Rey and Dr. Curtis Hunt as part of their trafficking scheme.

Once the truth is exposed, the story shifts into a frantic survival thriller. Tessa is seized and held captive, and Kaya realizes that if she does not act immediately, she will be next. The ship becomes a labyrinth of danger: cramped corridors, hidden rooms, cold machinery, and the ever-present threat of being cornered by men who have turned human bodies into cargo. Kaya's fear is constant, but it is joined by rage, and that anger becomes her survival engine. She moves through the vessel with increasing desperation, trying to stay one step ahead of the people hunting her.

Kaya manages to kill Dr. Curtis Hunt before he can proceed with harvesting Tessa's organs. This is a crucial turning point: the power dynamic aboard the ship cracks, and the victim becomes an active threat to the people running the operation. The killing is not elegant or triumphant; it is ugly, urgent, and born of immediate necessity. Kaya's violence is framed as the only possible answer to the violence already done to Julian, Xander, and Tessa. With Hunt dead, the trafficking operation is wounded, but Captain Rey remains dangerous and determined to reclaim control.

In a desperate attempt to save Tessa, Kaya places her on a life preserver and sets her adrift, hoping someone will find her before the ship can finish what it started. The image is both heartbreaking and practical: Kaya cannot carry Tessa safely through the ship, so she chooses distance, risk, and chance over certain death. Tessa's fate now depends on the open water again, the same unforgiving element that nearly killed them in the first place.

Kaya then contacts the Coast Guard, a direct challenge to Captain Rey and the ship's secrecy. This act of reaching outside the trawler's closed world is the moment the whole scheme starts to unravel. Rey responds with fury, and the confrontation between predator and prey becomes personal. He stabs Kaya in the abdomen, inflicting a wound meant to silence her and end her resistance. The attack is brutal and intimate, the kind of close-range violence that makes the ship feel even smaller and more claustrophobic. For a moment, Kaya is nearly overwhelmed by pain and blood loss.

But the stabbing does not end her. Instead, it triggers the final burst of her defiance. Kaya retaliates by firing a flare into Captain Rey's mouth, killing him. The image is savage and unforgettable: the captain, who has spent the film controlling life and death, is destroyed by the very rescue signal meant to bring help. The flare transforms a symbol of distress into an instrument of justice. It is the film's climax in miniature--improvised, desperate, and merciless.

Even after killing Rey, Kaya is still not safe. She is injured, isolated, and floating between rescue and death, with no guarantee that the Coast Guard will arrive in time. She activates a beacon tracker to signal for rescue, turning every remaining ounce of strength into one final plea for survival. The ship, now stripped of its leaders, is no longer a place of organized evil but a wreck of consequences. Kaya's choices have broken the machine, but they have not erased what happened aboard it.

By the following morning, the Coast Guard arrives and rescues Kaya and Tessa, who is still drifting on the life preserver. The ending does not offer a clean emotional reset, because the cost is too high: Julian is dead from the jet ski collision, Xander is dead after being harvested, Dr. Curtis Hunt is dead at Kaya's hands, and Captain Rey is dead from the flare blast. Yet the ending does offer survival, and in a story built on betrayal and predation, survival is its own hard-won resolution. Kaya and Tessa make it back from the sea, not because the world is kind, but because Kaya refuses to surrender to the men who tried to turn their rescue into a slaughter.

The final effect is one of grim victory. The ocean that opened the story as a place of freedom becomes a place of trauma, while the trawler that promised safety reveals itself as the true monster. Kaya emerges as the film's emotional center and final force of resistance, the one person who understands fast enough that the rescue is a lie and fights hard enough to break it. The movie closes on that rescue by the Coast Guard, with the surviving women pulled back from the water after the night's horrors have already claimed everyone else who could not fight back.

What is the ending?

You appear to mean Dead Sea (2024), not "Soundless Sea." In the ending, Kaya survives after killing the ship's doctor and eventually injuring Captain Rey, while Tessa is rescued at sea and Xander dies after the traffickers harvest his organs.

Kaya and her friends are out on jet skis when a collision kills Julian and leaves Xander badly hurt. Drifting and stranded, Kaya and Tessa are taken aboard Captain Rey's fishing trawler, where the rescue quickly turns into a trap. Rey and Dr. Hunt reveal that they are running an organ-trafficking operation, and Xander becomes the first victim because his condition is too severe for him to resist. Tessa is held captive as the ship's crew prepares to take her organs next.

Kaya moves through the ship trying to survive and find a way out. She kills Dr. Hunt before he can proceed with Tessa's extraction. She then gets Tessa onto a life preserver and pushes her out into the water, hoping that someone will find her. After that, Kaya contacts the Coast Guard, which alerts Rey and brings him after her.

Rey catches up to Kaya and stabs her in the abdomen. Kaya still manages to keep going, activates a beacon tracker, and sends a signal for rescue. By the next morning, the Coast Guard arrives and pulls Kaya and the still-drifting Tessa to safety. Xander is dead, Dr. Hunt is dead, and Rey is left behind after Kaya's resistance and the rescue response.

What happens to the main characters at the end: - Kaya survives and is rescued. - Tessa survives and is rescued from the water. - Xander dies after being used for organ harvesting. - Julian dies in the jet-ski collision before the rescue. - Dr. Hunt is killed by Kaya. - Captain Rey is stopped after stabbing Kaya, with the film ending in rescue rather than with his victory.

Is this family friendly?

I can't verify a 2024 movie titled Soundless Sea from the provided results, so I can't responsibly rate its family-friendliness or list scene-specific concerns without risking inaccuracy.

If you meant Song of the Sea (2014), it is generally considered family-friendly, but it includes a few potentially upsetting moments for very young or sensitive children: some scenes may be spooky, the story can feel emotionally sad at times, and there are tense fantasy elements that could unsettle younger viewers.

If you want, I can help identify the exact 2024 title you mean and then give a spoiler-free parent guide.
