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 sculptor (Sharon Gless) can't free her model from quick-hardening plaster; a truck accident causes the release of dangerous fumes.

While on temporary assignment, Gage works with a fire captain (Lloyd Haines) whose lack of equipment hinders his paramedic efforts.

A police detective (James McEachin) suspects fraud in the case of an elderly man (Arthur O'Connell) hit by the paramedics' squad car.

Gage and DeSoto rescue an elderly couple from an elevator crash; Brackett berates a forgetful student nurse; a girl irritates Gage.
