back in the 1990's i watched a movie but forgot about it till a few years later by then the rental store i got it from was gone this movie is about two brother who have learnt ninjitsu (i think) and have been doing the dim mak/death touch - as i recall there is 2 maybe 3 films deff 2 , its called either Dim Mak, the touch of death , death touch . here is a breif discription of the scene from the film -
during the film the lad performs a ritual (bit like Daniel Larruso in the karate kid) his hands move str8 out sideways then he moves them above his head and down to his chest, he then he moves his right head around his left and with his index and middle finger he hits a bad guy in the film the movie shows a colour of lighting serge around his fingers and hit the bad guy.
