A madam uses underage girls to extort credit cards from the Johns -- but even she has to ask for McCloud's help when one of the girls gives birth and is stalked by a robber-killer posing as a Minnesota sheriff.
A black gang infiltrating a white ethnic gang's numbers racket makes four very big mistakes, in ascending order of importance: robbing and killing a pickup man for his bets and the numbers; shooting Broadhurst (knocking him out of the episode after the first scene) when he tries to interfere; framing the unconscious Broadhurst for skimming money from the numbers runners; and depriving a VERY well-connected Jewish tailor of his winnings.
On temporary assignment with the NYPD Mounted Police, McCloud and a nervous policewoman botch the attempt to capture a group of radicals who stole a huge cache of weapons -- so both go undercover posing as crazed gun buyers.
When a drug lord who strongly resembles McCloud disappears after a by, McCloud assumes his identity, goes to prison, and tries to con the crime family who was setting up a French Connection with the drug lord.
McCloud goes undercover to trap a ring of vicious loan sharks, investigate the murder of a Navajo woman who was indebted to them, and free the innocent man who is blamed for the murder, all while stepping on the toes of the soon-to-be-retired detective assigned to the case.
In the second "Alamo" episode, Phyllis Norton, in her last appearance, takes over the station when Chief Clifford catches the flu, a thief kidnaps Broadhurst in order to swap him for the thief's brother, a drug-addicted mother kidnaps her addicted newborn daughter - and a time bomb ticks in the squad room ceiling.
