Ken Sakura(Michael Beck) is a successful art dealer with a secret.
Abandoned as a child, he was raised by a Japanese man Maturo(Mako) and
his family. When Maturo's two sons die in the Korean War, he decides
to teach his adopted son the ways of becoming a ninja. Upon reaching
manhood, Ken adopts the persona of The Last Ninja. Using his ninjitsu
skills, he dedicates his life to secretly fighting crime and defending
innocents, alongside his adoptive sister Noriko(Nancy Kwan). When a
group of top scientists are taken hostage in Houston, a federal agent
Cosmo(John McMartin) tries to recruit Ken to contact The Last Ninja,
unaware they are one and the same person. Ken a.k.a. The Last Ninja
decides to lead a daring one-man raid to free the hostages. With good
action sequences and an interesting plot premise, The Last
Ninja was promising pilot for a television series, with Nancy
Kwan in a recurring role, that unfortunately never materialized.
