Jerry and Sammy's parents are archaeologists, and this summer they've been given the chance to attend a dig in China, and the children are to go with them.

But as soon as they get to China Sammy begins having visions. Whilst Jerry loves finding out about the Mongolians near to the dig, Sammy is busy trying to find out why she keeps having visions.

All of her questions are answered when they dig up an old hair slide.
