The Sand Castle is a slow-burning psychological thriller that delves into the harrowing effects of PTSD, particularly in war survivors—especially children. The film opens with a family—Jana, Adam, Yasmine, and Nabil—stranded on a remote island. At first, Jana sees this place as a paradise, a fleeting escape from the horrors of their past. But for Yasmine and Nabil, the island is a prison, and they are desperate to find a way out. The only one who truly grasps the gravity of their predicament is Adam. As days pass without food or water, Yasmine and Nabil’s grip on reality begins to slip. In their descent into madness, Adam steps up—struggling to keep his sister Jana safe while searching for a way to reach the other side of the island, where hope for rescue may still exist.

The Sand Castle (2025) Plot Summary & Movie Synopsis:
“The Sand Castle” opens on an isolated island. Young Jana considers this land her home. This piece of land is Jana’s paradise, hidden from everyone. In this land, Jana has become one with her surroundings and calls the blue sea a monster that tries to lure you in, especially at night. This blue monster shows you precisely what it wants you to see. On this island, Jana lives with her parents, Yasmine and Nabil, and her elder brother, Adam. One day, Yasmine tries to find the right radio frequency while looking at the horizon with binoculars. At the same time, Jana is building the foundation of a sand castle. Inside the house (a part of a lighthouse), Yasmine and Nabil argue whether someone will show up and rescue them.
What does Jana find beneath the sand?
During supper, the family has very little food. While Jana tries to be positive, thinking something is better than nothing, Adam is curious about why his parents are pretending everything is normal. To change the subject, Nabil looks at Jana’s drawing, where Jana drew something she thought she saw in the sea. Hearing this, Adam starts bickering with Jana. After supper, Yasmine promises Adam that it will be their last night on this island as people are coming to rescue them. In an attempt to get help, Nabil and Jana turn on the lighthouse light to let anyone in the sea know that people are stranded on the island.
At bedtime, Jana asks Adam if he thinks of ‘her’ before going to bed. The question is met with silence. Meanwhile, Nabil gets the radio to work, hoping they can contact any ships to help rescue the family. The following day, assuming someone is coming, the family waits by the shore. After waiting a long time, Nabil heads back to the house to try to contact the ships again. At that time, Jana plays in the sand and comes across something hard beneath it. Curious about this strange object, Jana pokes a hole in it. As soon as Jana does that, the lighthouse light stops working. When Jana places her ear on the hole, she hears some screams. At that moment, Yasmine calls out to Jana, so Jana covers the surface with sand and rushes home.
Why is Yasmine on the edge?
As Yasmine tries to contact people using the radio frequency, Adam jumps into the sea. Now, Nabil is worried as he looks at his family picture. In the photo, we see three children, Nabil and Yasmine. As a last resort, Nabil prays to Allah and asks for forgiveness. Later, Adam and Jana bring a huge turtle, hoping to keep the animal with them. A troubled Yasmine scolds the children for going into the sea and asks them to leave the turtle back into the ocean. As the days pass, Adam gets frustrated and wants to leave the island. Since Yasmine has yelled at Adam, she tries to make up with her son. The duo listens to music, and Adam teaches a few dance moves to Yasmine.
When Adam jumps into the sea, he sees some squids. Since they are running short of food, Adam suggests they catch some squid. The next day, Adam and Nabil head to the sea to catch some squid. As Nabil dives deeper into the ocean, he sees a dead girl, which scares Nabil to his bones. Immediately, Adam comes to Nabil’s rescue, but Nabil’s leg is already injured. A while later, Jana brings a small girl’s red shoe home. It is the identical shoe Nabil saw underwater. For everyone’s sanity, Yasmine buries the shoe in the sand. Frustrated, Yasmine heads down to the basement to fix the generator while Nabil tries to get some contact from the outside world. While the parents are getting frustrated by the minute, Adam looks after his sister.
Why does Adam take charge of the family?
There is a thunderstorm that night. Once the rain reduces, Adam goes out and sees that they have accumulated fresh water. After all these helpless days, something good happened. As Nabil is injured, he cannot get up and do much, making Yasmine miserable. Suddenly, they realize Jana is not to be seen. So Yasmine goes out and sees Jana drowning in the sea. Yasmine jumps into the water and carries Jana towards the shore. However, as Yasmine moves towards the coast, she sees Jana standing by the shore. Hearing Jana’s screams, Adam runs to the ocean but cannot save Yasmine’s life.
After this incident, Adam tries to get some signal from the ships but fails. Next, Adam makes some kites with long strings. As the days pass, Nabil gets sick and craves coffee. However, Adam knows his father is hallucinating and gives him an empty cup. Even though there is nothing in it, Nabil drinks from it and is pleased as he thinks he drank coffee. Meanwhile, Jana is sleeping and dreaming about rows and rows of dead bodies. As the dead body rows end, Jana sees a building on fire. Suddenly, Nabil hears Yasmine’s voice, so he limps and crawls to the shore. There, Adam sees Nabil and tries to get him back inside, but Nabil sees a woman in the sea and dies.

A Fading Hope and the Echoes of the Past
The only one Jana has is her brother Adam, who does his best to calm Jana down. As Adam asks Jana to take deep breaths, Jana thinks of the happy times. Now, Jana and Adam let the kites fly, hoping any passing boat/ship can see it. There is some radio connection, and Adam gives the men on the other line his coordinates. By then, Adam also starts to hallucinate and is exhausted. In that exhaustion, Adam remembers the broken buildings. Suddenly, Jana and Adam see a ship and start calling out to it. Unfortunately, the boat doesn’t arrive at the shore. So Adam runs into the water, swimming towards the ship. Now, Jana is left all alone on the island.
At this moment, Jana remembers things of the past, especially her sister Yara. In one memory, her family asks Jana to bring Yara for a group picture. Another memory is that Jana and Yara are having a lovely time in school. Suddenly, a bomb falls on the school building, killing Yara immediately. When Jana wakes up, she meets with Yara, and the sisters hug each other.
Can Imagination Be a Refuge from the Wounds of War?
At the same time, the whole island is consumed by the ocean. In the final scene, we see Jana on a lifeboat, the same one she found under her sand castle. Post Credit says “This film is dedicated to those forced to live in their imagination. ‘Nearly 500 million children worldwide live in areas affected by armed conflict. They live in constant fear, experiencing grave violations of their right including forced displacement with serious impact on mental health.”
At first glance, The Sand Castle appears to be a stark portrayal of what happens when basic human needs go unmet. However, beneath its surface, the film unfolds like poetry—its frames and narrative delicately weaving a story about the lingering trauma of those who have survived war. Told through the eyes of a young girl, Jana, who has lost her family to war, the film explores how she clings to her imagination as a means of survival.
The story captures the quiet despair of a family stranded on a desolate island, their hope for rescue fading with each passing day. A haunting sense of melancholy pervades their existence, as they yearn for salvation that never comes. In the end, the ocean swallows them whole—a cruel reminder that some wounds of war can never truly heal. For Jana, the ghosts of her past will never fade. She remains trapped in a cycle of memory and loss, her only refuge being the world she creates within her mind. The Sand Castle masterfully encapsulates the grief of those left behind, painting a poignant portrait of a child forced to reimagine life in the aftermath of war.
