Kung Fu charts the adventures of Kwai Chang Caine, the son of an American sailor and a Chinese woman who spent his childhood years at a Shaolin monastery. 

Kwai Chang Caine is left with no choice but to take bloodied revenge on the Chinese emperor's nephew after he guns down his master, Master Po (Keye Luke). He flees to the U.S. partly to escape punishment and to reunite with his long-lost brother, Danny Caine (Tim McIntire). 

In Season 3 of Kung Fu, Kwai Chang Caine picks up the fight with the members of "The Order of the Avenging Dragon," who follow him to the U.S. to avenge the death of the emperor's nephew. In the last batch of episodes, Kwai Chang Caine provides much-needed help for the vulnerable and disenfranchised, while he also manages to arrange a meeting with his long-lost brother, Danny.
