Adam-12 - Season 7 Episode 4

An 'officer needs help' call comes in with no callsign or location. The dispatcher starts a division wide radio "roll-call" in order to account for every officer on patrol. While the roll-call is going on, calls for service from the public still needs to be handled. When a motorcycle officer fails to check in when prompted, a division wide search is instituted to look for him, which Malloy & Reed are assigned to assist in.
