The doctors at Rampart set their sights on a diabetic patient who, intentionally or otherwise, repeatedly forgets to take his insulin shots. Another crisis situation arises from a frantic phone call from an anonymous woman who claims to have overdosed on drugs. Elsewhere, the team attempts to rescue some valuable horses from a burning stable; a hostage in a bank robbery is given medical treatment literally "under the gun"; and fireman Chet Kelly (Tim Donnelly) tries his hand at guitar playing. ~ Hal Erickson, Rovi
