Plot
Big Boss’ crooks make themselves invisible to make things difficult for the COPS team to catch them and have an easy time committing robberies in the process. This episode features Mace being highly annoyed by Airwave and his constant babbling. Airwave is the newest member of COPS who serves the team as a communications expert and could make an excellent sportscaster if he hadn’t chosen to be part of COPS.
