"In this all-new very special miniseries, the Aldens have been recruited by a secret society to return lost artifacts and treasures to their rightful locations―all around the world! The final leg of the Aldens' journey brings them to South America and to the Salt Flats in northern Argentina. But when they hit a dead end, they realize someone has tricked them in order to delay their plans! Returning to Buenos Aires, the Aldens connect with the Silvertons and are able to get back on track. But it is clear their rivals are closer than ever. The Aldens' final artifact is their most delicate yet―a rare orange orchid they must return to Machu Picchu in Peru. With the stakes higher than ever, the Aldens make a shocking discovery about the Silvertons and the Argents. Will the Boxcar Children be able to use what they've learned to return the final Reddimus artifact intact?"
"The Aldens chart a course for their next adventure - Australia and Antarctica!
As the children tour the famed Sydney Opera House, their next puzzle - and its key - falls right into their laps. They need to find the rightful owner of a rare Australian coin. Using their knowledge about Australia, the Aldens find the coin's owner, but a saboteur is again hot on their heels and nearly spoils their hard work.
Next up, the Aldens travel to frigid Antarctica, where they need to return an artifact to the hut Shackleton used on his expeditions to the South Pole. The trip is a success, but when they Aldens return, they learn the identity of the person who has been trying to ruin their plans. Will the saboteur keep them from returning the seventh and final artifact."
"Henry, Jessie, Violet, and Benny chart a course for China to return the Reddimus Society's fourth artifact!

Then, after an unexpected stop in Thailand, they meet a suspicious man claiming to work for the Reddimus Society. The Aldens wonder if someone close to them is working for the other side. Who can the Boxcar Children trust to help them?"

As the children travel through Egypt, Kenya, England, and Italy, can they stay one step ahead of those trying to sabotage their plans?"
