The Kur Stone:Part One was the series premiere of The Secret Saturdays. It premiered on October 3rd, 2008.
V.V. Argost returns looking for the Kur Stone, an ancient relic that was taken from him by The Secret Scientists a decade ago. Despite managing to steal two of the pieces from Dr. Miranda Grey and Dr. Henry Cheveyo, the Saturday family have hidden theirs. Returning from South America and discovering his plan, the Saturdays go to see Cheveyo. Discovering that Argost used a Neural Parasite on Dr. Cheveyo, and that they revealed the location of the last piece to him, they must get to Brazil. That is, if they can survive the Firecracker Beetle trap Argost made for them.
