I remember this series quite well. Back in the 80s when the US underwent a "ninja" phase, this came out. Lee Van Cleef is an American trained as a ninja who decides to leave "the family". Sho Kosugi (a real life kick butt martial artist) goes after him. Cleef comes to America and meets up with Tim Van Patten who joins up as his apprentice, hence, the title. It's kind of cheesy, but not as bad as it could have been. A lot of the "wandering do-gooders" a la "The Incredible Hulk" and "Scooby Doo". I remember watching this on Friday nights and enjoying the heck out of it.
