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.

During their Christmas Eve Patrol, Malloy and Reed contemplate using their patrol car to deliver a Christmas tree to the residents of a soon-to-be-closed retirement home. Meanwhile, an elderly man's bagpipe playing is considered a public nuisance, a couple of teenagers steal a delivery truck containing radioactive material, a nervous man is desperate to cover up the smell of perfume on his clothing and an armed robbery suspect becomes intent on committing suicide-by-cop.
