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.

DeSoto and Gage talk down an airplane flown by a teenage boy whose father, the pilot, suffered a heart attack while at the controls.

Various crises faced by animal-control officers (Mark Harmon, Albert Popwell) bring them to Rampart General; guest David Huddleston.

The paramedics hold a demonstration for student nurses, one of whom interests Gage; the hospital staff saves a robber and his victim.

Gage begins a rocky affair with a stewardess (Gretchen Corbett) who asked his and DeSoto's help with an in-flight heart-attack victim.
