Blue Monkey

Fred Adams visits Marwellia Harbison's greenhouse and notices a drooping yellow-flowered plant said to originate from a newly formed volcanic island off Micronesia. Marwella explains its origin and hints that there is more to the plant than meets the eye. The scene sets a creeping sense of danger tied to the plant.

Fred accidentally pricks his finger on the plant, though Marwella insists the plant has no thorns. The injury is mysterious and unnerving, suggesting a hidden hazard. This moment plants the seed for the subsequent inexplicable illness.

After bidding Marwella goodbye, Fred collapses near his truck, and he begins to feel strange almost immediately. Paramedics are called to the scene and he is rushed toward medical care. The sudden collapse marks the first in a chain of alarming events.

At Hill Valley Hospital, Fred is admitted with a very high fever and gangrene forming at the prick site. Doctors Rachel Carson and Judith Glass are baffled by the rapid progression of the infection. The case draws attention away from other trauma arriving at the same time.

Detective Jim Bishop arrives with his partner, who has a gunshot wound from a stakeout gone wrong. The medical staff must manage the new trauma while Fred's mysterious illness dominates the scene. The police presence adds to the hospital's mounting tension.

Fred convulses and vomits an insect pupa, which is sealed in a bell jar in the hospital's in-house laboratory. The discovery confirms there is more than a standard illness at play. The team begins to suspect a parasitic link between the plant and the infection.

Concern about contagion leads to mandatory checkups for staff and patients, including Jim. Rachel guides Jim on a tour of the hospital's high-tech research wing, illustrating the advanced lasers and equipment used in modern surgery. The atmosphere grows tenser as fear of an outbreak spreads.

Efforts to image the pupa fail, so the team decides to slice it open. The insect within proves aggressive, forcing containment with Jim's help. The lab scramble escalates as the creature proves dangerous beyond expectation.

Fred's condition worsens as parasites spread and he goes into cardiac arrest. Judith Glass attempts to revive him with shock paddles, but his chest explodes in a violent collapse. Marwellia and the paramedic who brought Fred in begin showing the same alarming symptoms.

Marwellia Harbison and the hospital paramedic who brought Fred in fall ill with the same mysterious symptoms. The outbreak now threatens both staff and patients, heightening the urgency of containment. The hospital leadership must confront a rapidly spreading mystery.

Hospital director Roger Levering resists quarantining the facility to avoid panic. Rachel's determination persuades him to bring in entomologist Elliot Jacobs to identify the insect. The investigation expands beyond immediate treatment to scientific understanding.

A group of pediatric patients wanders into the lab after the insect is left unguarded. Lab tech Alice Bradley is distracted by her boyfriend, Ted Andrews, and the insect goes unmonitored. The children pour a bluish growth-hormone powder into the specimen, causing the insect to swell to giant size and kill the nurse and the orderly.

Elliot Jacobs arrives and, with Rachel and Jim, discovers the powder was a growth hormone. The giant insect is now in the hospital's utility tunnels, killing a janitor as it begins to nest. The team races to locate and stop it before it can spread further.

The trio devises a plan to halt the insect while Judith fights the disease spreading through the building. The Lincoln Institute calls in the military to contain the outbreak, signaling a shift to large-scale intervention. A coordinated effort is set in motion to prevent a full-blown disaster.

In a drastic measure, the military destroys the hospital facility to stop the spread of the infestation. The action ends the immediate threat but leaves the complex in ruins, forcing those who survived to confront the aftermath and what the outbreak revealed.
