A repairman is infected when his hand is "cut" by a certain flower which causes something encased in a cocoon to exit his mouth while he's unconscious in an emergency room of County Memorial Hospital. This causes an infection which soon leaves paramedics who brought the victim to the emergency room to become unconscious and afflicted as well. Detective Jim Bishop(Steve Railsback) enters the emergency room with a partner who was shot during a stakeout which went awry. Along with Dr. Rachel Carson(Gwynyth Walsh)and entomologist Elliot Jacobs(Don Lake), Bishop will have his hands full as hospitalized kids being mischievous enter the lab holding the cocooned insect, feeding it a large dose of NAC-5, an accelerant growth promoter, because they thought it was hungry and needed nourishment, which works as a catalyst in metamorphosing it to a substantial degree, now an insect monster on the rampage. The Lincoln Center for Disease Control(working with Department of Health) puts County Memorial Hospital under quarantine and burns down the greenhouse which contained the flower behind the insect. Developments emerge which includes the fact that a bottle of Jack helped stop the toxins(caused by the infection) from spreading throughout the bodies of two elderly ladies who get wasted, an audio recording by Elliot of the giant insect mate's "voice" actually interrupts its path towards killing Bishop, County Memorial has a laser research lab(Laser research is the wave of the future Dr. proclaims) for future benefits in molecular breakdown and DNA experiments which will be used as a method to distract the creature, and we are informed through the entomologist that future insects will breed at an alarming rate(feeding from humans slowly, as we see in the case of a nurse and scientist who are cocooned and eaten from!). Essentially a "giant bug" movie with Railsback up against an insect which walks upright and beheads innocent victims who cross its path. I think this film has a bad rep due to its ridiculous title, because BLUE MONKEY(the alternate title, INSECT, is actually more logical)is more or less reminiscent of other 50s giant insect titles, except in a modern 80s setting. The creature is darkly lit and carefully edited as it causes mayhem obviously so that it wouldn't cause chuckles if seen clearly. Railsback gets to play hero again, but will need help from Walsh and Lake if he is to conquer the fiend and its offspring. Susan Anspach is another emergency room doctor, Judith Glass(she's the one who discovers the solution to the outbreak)and John Vernon is the hospital administrator(not as much an asshole as he normally is in other movies). Joe Flaherty and Robin Duke are a couple expecting the birth of their first child, a sub-plot which has no reason to be in the movie, to tell you the truth, other than to add some comedy.
