Princess Gonzales is a young law graduate who signed up with the National Bureau of Investigation as a rookie agent. Her dedication to her work is fueled by a desire to find out what happened to her father, who disappeared several years before and is presumed dead. Her performance later earns her an assignment with the NBI's EAGLES (Elite Agents of Government Against Lawless Elements of Society) squad, where she is paired up with veteran agent Ambet Katindig as they handle tough missions. Although Princess and Ambet's work ethics clash throughout the series, their bond develops into a relationship by the end.
