The dedicated members of Squad 51 of the Los Angeles County Fire Department's newly created Paramedical Rescue Service take on a series of life-or-death challenges in this drama filmed in semi-documentary style. Partners John Gage and Roy DeSoto put their lives on the line to save people from all sorts of mishaps.

A televised demonstration of fire-prevention techniques winds up with Gage and DeSoto in the middle of a real-life medical emergency.

Gage and DeSoto buy a battered 1932 fire engine; the hospital staff deals with a gunshot victim and a bigamist; guest Yvonne Craig.

The paramedics dread an upcoming inspection by their reportedly strict battalion commander; an accident traps teenagers in their car.

Gage is chosen to take in a litter of kittens; a girl's father dies in an airplane crash that also injures his wife (Brooke Bundy).
