Ghassan Al Ghurairi had to accompany his old grandfather to the Leewy Museum in the middle of the desert. They are attending a ceremony honoring his grandfather, who spent his entire life in service of the desert. As they head to their destination onboard an ancient train, Ghassan came across a conspiracy plotted by the criminal Aqrabawi and his bald friend— disguised as two elderly women—to poison the oasis’s water supply. In place of the ecological life in the desert, they want to make way for an international resort and take over the place.

Although Ghassan doesn’t mean to confront this conspiracy alone, he finds himself embroiled face-to-face with the criminals. Fortunately for him, a girl appears at his side to help. Sophia Al-Adnani from Chiparazumpia is also heading with her grandfather and his great eco-friendly invention, the glass ball, to the Leewy Museum, where her grandfather is to be honored.

The two children are able to hold off the criminals initially, but not for long, as Aqrabawi and his friend soon reappear—this time deadest on revenge against the two children. Ghassan and Sophia resist in the face of intimidation and threats, and, using clever intrigue, they manage to disarm the conspirators and escape seconds before the desert guards arrive and arrest the criminals.
