ATAC sends Frank and Joe Hardy to investigate a possible connection between two unusually harsh accidents at a nearby Martial Arts school. Enrolling in the school, of course, allows the guys to collect some serious clues – and to discover that this case may lead them dangerously close to their own circle of friends.
