Three rookie cops adjust to life in Southern California.

A young man suffering from a split personality perplexes Terry and Willie, but is the cause of extreme danger for Mike and Ryker.

Willie becomes infected with meningitis from a pair of former convicts who could cause a city-wide epidemic; guest Anthony Zerbe.

A felon demanding his convict partner be freed holds Terry and three women hostage in a bank vault; guests Tyne Daly, Robert Walden.

Terry and new rookie Chris Owens (Bruce Fairbairn) seek an arsonist responsible for killing dark-haired, mustachioed firefighters.
