A martial arts rock band goes up against a band of motorcycle ninjas who have tightened their grip on Florida's narcotics trade.
The year is 1987. Motorcycle ninjas tighten their grip on Florida's narcotics trade, viciously annihilating anyone who dares move in on their turf. Multi-national martial arts rock band Dragon Sound have had enough, and embark on a roundhouse wreck-wave of crime-crushing justice. When not chasing beach bunnies or performing their hit song "Against the Ninja," Mark (taekwondo master/inspirational speaker Y.K. Kim) and the boys are kicking and chopping at the drug world's smelliest underbelly. It'll take every ounce of their blood and courage, but Dragon Sound can't stop until they've completely destroyed the dealers, the drunk bikers, the kill-crazy ninjas, the middle-aged thugs, the "stupid cocaine"...and the entire MIAMI CONNECTION!!!—MiamiConnection
In a world where ninjas dream of being rock stars and rock stars dream of being ninjas, a martial arts rock band goes up against a band of motorcycle ninjas who have tightened their grip on Florida's narcotics trade. Who will emerge victorious and neon-lit?
A cocaine deal in Miami is interrupted by a group of motorcycle-riding ninjas led by Yashito, who steal the drugs and ride back to Orlando to party. At a club, Yashito's close associate, Jeff, sees his sister Jane onstage. She has become romantically involved with John, the bassist of the club's band, Dragon Sound, which consists of an ethnically diverse group of five college students who are best friends. They live together, train Taekwondo together, attend University of Central Florida together, and are all orphans. Jeff disapproves of his sister's relationship with John and confronts him at school, but Mark, rhythm guitarist of Dragon Sound, and Taekwondo instructor and father figure to the other band members, stands up to him.
Another band confronts the owner of the club over his hiring of Dragon Sound, but gets beaten up. The band leader brings a large group of rowdy guys to Dragon Sound directly and fights them in the street, but Dragon Sound defeats them with Taekwondo. Consequently, the rival band enlists the help of Jeff, who summons Dragon Sound to fight at a train depot, but he and his gang are badly defeated by Dragon Sound's superior martial arts skills. Jeff tries again by kidnapping Tom, the lead guitarist and singer of Dragon Sound. The remaining band members stage a rescue, wherein they free Tom and accidentally kill Jeff. Yashito is angered by Jeff's death and sets out for revenge.
Meanwhile, the keyboardist of the band, Jim, has revealed that he is searching for his long-lost father. He finally receives word that his father has been located, so the band pools their money to buy him a suit and then heads to the airport. Along the way, Yashito and his gang of ninjas surround Mark, Jim and John and chase them into a park, where they do battle. Jim is critically injured, but John and Mark manage to kill all of the ninjas, and Mark kills Yashito in single combat. At the hospital, Jim survives his wounds and reconnects with his repentant father.
