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 rattlesnake bites Gage during a mountain rescue; opposition greets the paramedics when they try to help victims in another state.

Fire, police and paramedic units respond to a major accident pileup snarling rush-hour traffic on a fog-shrouded stretch of freeway.

Paramedics out in the field begin to question the judgment of overcautious Dr. Morton who believes in acting strictly by the book.

Gage suffers from insomnia; a man reports his friend is in critical condition after they both smoked marijuana; guest Ronnie Schell.
