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.

Gage promises to care for an injured woman's dog; the paramedics save five lives including a diabetic and a man trapped on a ledge.

A temporary fire captain (John Anderson) is disdainful of the paramedics' rescue methods; Brackett subdues a violent motorcyclist.

An injured cameraman proves to have more than a broken leg, leading Brackett to search for a botulism source; guest Susan Seaforth.

A day of serious incidents is broken by Gage's assignment to conduct a group of inquisitive schoolchildren on a tour of the hospital.
