A rollicking race between a battalion of British nannies and London-based Chinese Intelligence agents to find a microfilmed international secret hidden on a museum dinosaur skeleton makes for all sorts of good humour. Full of suspense, this light-hearted comedy skips and slides through one outrageous situation after another... not the least of which is the sight of the mammoth skeleton loaded on the back of a steam wagon as it's chased through the streets of London!
