A family with three children lands on a planet where the desert moves like a living ocean. The kids race down dunes that rise and fall like waves, while their parents watch sky islands drifting overhead. Beneath a transparent sea of sand, gardens of coral-shaped fruits glow in impossible colors. Quiet, crystal-eyed creatures follow them like kind guides through this strange landscape. At night, a market fills with light and music, and the locals invite them to share food and stories around the fire. Under liquid moons dripping silver light onto the desert, this simple vacation becomes a memory that will guide them through the stars.
