France 1705. Captain Daniel Rawson is always ready for an adventure, so when Duke of Marlborough proposes a dangerous undercover mission to discover what happened to one of their spies, a Dutch tapestry-maker, Rawson happily accepts. He journey's to France in disguise, and is delighted to find a lovely distraction in the form of the tapestry-maker's beautiful daughter. Unaware of her father's espionage role, Amalia is fearful for his safety and it's up to Daniel to find her father and put Amalia's mind at rest.

Meanwhile, Rawlson's stalwart is Sergeant Welbeck is left in camp with complications of his own. His wide-eyed nephew has joined the army as a drummer boy in pursuit of honour and glory. Welbeck would like nothing more than to ignore this eager young boy, but circumstances are conspiring to make this impossible.
