Yusuf is like any other 10-year-old boy living an ordinary life with his parents. He likes nothing more than spending time with his best friend Jack. Eight years after Yusuf's one and only trip to see his grandfather, the Ayouch family excitedly prepares to welcome Grandpa to England, at last! But even Jack has to agree that the gift that Grandpa brings Yusuf from Morocco is disappointingly ordinary. Or is it?

Little do the boys know that together they are about to discover a world so much bigger than either of them ever imagined and learn how, with a curious mind, things are not always what they seem. But will it finally teach them to appreciate the most valuable gift of them all?
