De la película hay muy muy poca información, pero bueno... os dejo la reseña de Kurotokagi:
A dangerous pact has been signed by Tadanaga, the son of Shogun Hidetada, to prevent his brother Iemitsu from becoming the third Shogun. In a time where highly skilled ninja organizations carry out secret missions, Iga Jigoza's group of seventeen ninja must find a way to infiltrate the enemy's stronghold and steal the pact from Negoro ninja Saiga Magokuro. A classic, a must have for any fan of ninja movies!
