Plot Synopsis:
Tao, a ninja from the Iga clan, wakes up in a cave surrounded by dead bodies, including a beautiful female ninja. Suffering from amnesia, he can’t remember how or why he’s there, or if he’s the one responsible for this massacre. His task at hand is to retrieve a document that will reveal the killer’s identity. Who is the killer? Was one of his clan a traitor? Who is the female ninja?
As Tao fights various other ninja, he begins to piece together his memories with their stories. But instead of solving the enigma, a web of betrayal unfolds.
