This is an excellent example of a Relic Hunter episode.
It sees Nigel and Sydney looking for a jade coffin of which a piece has been published in a remote newspaper. The jade coffin was meant to hold a Chinese princess who wasn't able to be buried next to her beloved emperor because thieves stole her coffin to get a priceless necklace.
This episode also saw Nigel getting hit on and he trying to see whether Sydney is interested in him after Claudia says their star signs are compatiable.
A few ex-lovers of Sydney also turn up wanting to find the necklace, but only one will be able to keep it in the end.
