While on a summer vacation in Japan, college student Justin Toshi Blackwood attends a lavish twenty-first birthday party for his cousin Kaito Saito. The two young men share a great-grandfather and soon realize each has inherited a mysterious family heirloom with one receiving a folding knife and the other a pocket watch.
After discovering the knife opens a secret compartment in the old watch containing a tiny hidden map, they hike out it into the forest along a riverbed to locate a jar containing the Nine Stones. Each grayish-blue river rock has an animal engraved on one side and a location etched in kanji on the other.
So begins an exciting international scavenger hunt where the two cousins must collaborate their efforts during supernatural encounters of recovery. Along the way, they unite with Justin's loyal sister Melia and new friend Yori as the four companions try to unlock a magical family secret. Will they survive the perilous journey and unravel the mystery?
