Former professional karate fighter Michael Rivers (Mathis Landwehr) has achieved numerous major victories. He ends his career at the peak of his abilities and, thankfully, physically intact, with no plans to return to the mat. One day, however, he receives an offer from the rather shady businessman Ron Hall (Matthias Hues). For a substantial sum, he is to participate in an illegal kumite tournament in Bulgaria, fought to the death, against some of the best martial artists in the world. Naturally, Michael rejects this offer rather brusquely.
