The Walker family assembles in the chronicle room to hear a story from the 3^rd Phantom's early years in which the reason for the massive drinking cup of pure diamond ending up in the "big" treasure room is revealed. (This strong-willed ancestor is also portrayed in S084 The Wig.)

The adventure starts when the 3^rd Phantom reluctantly agrees to escort the young Princess Pura to a Sultan's palace for a political marriage. However, the distraught Princess has other ideas, leading to completely unforeseen complications during an eventful return journey...
