AngryTownsman’s review published on Letterboxd :
Karate Kill is a fun, low budget martial arts film from the Director of Gun Woman.
Kenji is working multiple jobs in Japan and sending money to his sister, Mayumi. He goes a month without hearing from her and heads to the US to find her. This leads to Kenji fighting his way from California to Texas, and finding out the fate of his sister.
I highly recommend that you watch this movie. It is available on Video on Demand and on bluray and dvd. The bluray comes with a soundtrack cd.
