Táto séria sleduje osudy štyroch súrodencov, ktorí sa po strate rodičov ocitnú sami a nájdu si nový domov v starom, opustenom vagóne. Deti sa učia žiť nezávisle, riešiť problémy a budovať si vlastnú komunitu, zatiaľ čo sa postupne zoznamujú so svetom a jeho obyvateľmi. Príbehy zdôrazňujú dôležitosť rodiny, vynaliezavosti a odolnosti tvárou v tvár nepriazni osudu. Každý diel prináša nové dobrodružstvá a ponaučenia o spolupráci a objavovaní.
The Aldens are spending their first week of summer at Camp Quest in Colorado. The children are excited to learn about fossil hunting and paleontology from renowned scientist Dr. Iris Perez. But strange events at the camp make them wonder if the legends of a bigfoot-like creature roaming the valley might be more fact than fiction. Can the Aldens help Dr. Iris figure out who—or what—is causing such a stir?
The Aldens have joined Dr. Iris Perez as she investigates legendary creatures around the world. In this adventure, the children travel to Iceland to look into stories of mischievous elves causing trouble. The legends of huldufolk, or hidden people, go back a long way in the country, but are elves really the cause of the problems, or is there a more natural explanation for the strange events on the island?
