Hawaii Five-0: “Kekoa – Warrior”
Season 3, Episode 16 – February 11, 2013
“Kekoa” is Hawaiian for Warrior or Soldier and the episode featured Lua, the traditional fighting system of the Islanders.
The bone-breaking system of Lua is one of the “secret arts” that was added to Danzan Ryu Jujutsu and Kajukenbo. There is a training sequence and fight scene with techniques that will probably look really familiar to most of you.
You can probably watch the episode here for free, once the ads finish.
Also a bit of trivia: Mark Dacascos -a well known Kajukenbo man- plays Wo Fat (the main Bad Guy) in the series.
