Medieval Japan. An evil daimyo lord has stolen treasures of the Imperial family and hidden them in his castle in an attempt to seize power. As a young shinobi apprentice you've decided to sneak into the castle, recover the treasures and return them to their rightful owners in an attempt to bring prominence to your clan. However, a member of a competing clan has also discovered daimyo's scheme and is on the same mission as you. Do whatever it takes to be the first to recover stolen items and bring honor to your clan.
