In this episode of the popular series, the basic story plot deals with a wealthy woman (Hillary Pritchard) who is in Grace Brothers and discovers that she has dropped a valuable jewel in the store. She offers a large reward. Mr. Rumbold (Nicholas Smith) tries (in his own way - with his own agenda) to organize the search for the missing item.
There is an attempt at cooperative searching but soon male v. female antagonisms, and class antagonisms (Captain Peacock - Frank Thornton - v. the others) splinter the attempt at cooperation. In fact, only one person (Mr. Grainger - Arthur Borough) seems willing to work with all the others. What follows is a typical "Mad, Mad, Mad, Mad World" every- person-for-him-or-herself attempt by the characters to find the jewel and give it to the woman first. This leads to several odd and humorous situations, such as Mr. Lucas (Trevor Bannister) trying to "surreptitiously" put his foot over the jewel, without Peacock (who is standing over it) noticing Lucas' foot between his own.
But soon missing jewels turn up with alarming frequency, and the question arises of not so much who will find the jewel but which one found the actual jewel in question. As in most episodes the arrival of Young Mr. Grace (Harold Bennett) helps settle the matter, but also prevents everyone from getting what they wanted.
