A nice exploration of the samurai-ninja aspect of the story, including its roots in the actual Marvel comic books. There are the requisite interviews with the principal cast and crew along with copious clips from the film as well as some behind the scenes footage (including a look at that supercool metallic bed that the elderly Yashida lies on in the lab in his fortress).

A group of armed robbers fleeing the police head for the New Jersey Tunnel and run right into trucks transporting toxic waste. The spectacular explosion that follows results in both ends of the tunnel collapsing and the handful of people who survived the explosion are now in peril. Kit Latura is the only man with the skill and knowledge to lead the band of survivors out of the tunnel before the structure collapses.
