Meet Cody Jr., Casey and Conrad Hogan, nineteen-year-old triplets who are Arizona Rangers. Two are full-time police detectives and one is a peace-loving Ranger. They use their law enforcement knowledge and their martial art skills (each being a black belt) to fight for justice and truth, while promoting fair play. When their mother is car-jacked and beaten severely, the triplets, their father (a semi-retired Ranger) and their friend Detective and Ranger Tony Jordan track down the responsible parties, who soon find that this time they picked the wrong victim. This is one in many adventures to come.
