The series starred Lee Van Cleef and Timothy Van Patten, with recurring appearances by the star of the Cannon Ninja trilogy (Enter the Ninja, Revenge of the Ninja, and Ninja III: The Domination), Sho Kasugi. Van Cleef played John Peter McCallister, an aging Ninja Master returning to the United States to find his daughter. Kasugi plays his former student, Okasa, from Japan, who was out to kill him, and Van Patten plays Max Keller, who becomes his new student after the two meet in the mists of a bar fight. It is basically a story-of-the-week show where Keller and McCalister drive around the country looking for McCallister's daughter and eventually get involved in some local dust-up between (usually) a damsel in distress against the local bad guy(s).
The Blu-Ray set is a three-disc set. The A/V transfer is okay but not wonderful. It is about as good a transfer as you would expect for an old 1980s TV show that was canceled halfway through its first season. The only extras included on the set are trailers for a handful of the Westerns that Van Cleef was known for throughout his career, as well as trailers for Enter the Ninja and Revenge of the Ninja, the two movies Kasugi had been in at that point.
I think most people who will get this are those who were kids in the 1980s and remember watching it back then. You will definitely not get it because of great writing or acting. Several very recognizable and good character actors and actresses were in the show. Also notable is that a very young Demi Moore had a guest-starring role in the pilot. Still, it was overall a pretty hokey and cheesy show. The pilot episode was even featured in an episode of Mystery Science Theater 3000. The show's silliness is best exemplified by a scene in which one of the characters picks up a piece of uranium and sticks it in his pocket. Ultimately, if you watch it expecting it to be a fun blast from the past, it is enjoyable and even pretty funny. If you are expecting award-winning TV, you will be sorely disappointed.
