Food has run short in a prehistoric village, home to Bow, Sayaka and a cast of comic characters. To end the crisis, Inugami's grandmother gives a prophecy: a chosen one will rescue the village with the help of a great animal. Taking her words to heart, Bow, Sayaka, Inugami and Sabu head out on a journey together. Sayaka works hard to catch a mammoth, while Bow stirs up trouble by goofing around as he always does. The result is a lighthearted prehistoric adventure comedy, where an earnest goal keeps running into silly obstacles.
