With precious little time on their hands, the doctors at Rampart try to diagnose a mysterious ailment that has befallen a marijuana smoker. Elsewhere, the team rushes to a boat explosion; a worker is pinned to a wall by a semi; a boy falls in a gravel pit; and while trying to avoid running down a dog, a motorist and his son are seriously injured. No wonder John (Randolph Mantooth) is having so much trouble getting to sleep these days (actually, there are other reasons, but why give away too much of the plot?) ~ Hal Erickson, Rovi
