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 blackout forces fire rescuers Gage and DeSoto to take two women on a hand-over-hand descent down an elevator shaft.

Early undergoes open-heart surgery; the paramedics save one man trapped by a live power line and another (Dick Butkus) hit by a car.

Gage and DeSoto interrupt planning for their floor-polishing business to rescue an elderly hermit (Pat Buttram) trapped in a cave-in.

Gage must play a heart-attack victim's poker hand before the man will consent to treatment; an explosion rocks an abandoned refinery.
