Former Vietnam medic Ed Marlow (Robert Pratt) signs on as a paramedic trainee with Squad 51--and quickly alienates the rest of the staff with his smug know-it-all attitude. Marlow's ego-tripping proves particularly troublesome as he accompanies the staffers on a variety of emergency calls, involving a boy who has fallen off a cliff, a woman who has o.d.'ed on prescription drugs, and a diabetic with a bad insulin reaction. Former child star Jackie Coogan appears as a slovenly junkyard owner who learns the hard way to appreciate the local fire-prevention laws. ~ Hal Erickson, Rovi
