Moving to a new Wednesday-night slot for its fourth season, Adam-12 wastes no time getting down to business. This time, Officers Jim Reed (Kent McCord) and Pete Malloy (Martin Milner) are working the waterfront beat, where a nasty gang of extortionists specializes in targeting elderly Jewish businessmen. George O'Hanlon, better known to baby boomers as the voice of cartoon character George Jetson, appears as a vengeful drunk who makes some very bizarre threats against the two cops.
