Invasion of the Bee Girls

Neil Agar arrives in Peckham, California to investigate the death of John Grubowsky at Brandt Research. He quickly befriends the lab's head librarian Julie Zorn and begins interviewing the scientists, setting the stage for a broader mystery.

As the investigation progresses, a troubling pattern emerges: several men die of congestive heart failure that appears linked to sexual activity. Agar notes the deaths cluster around the laboratory and hint at a systemic cause rather than random misfortune.

Captain Peters hosts a town meeting to address the deaths. Henry Murger urges sexual abstinence as a solution, but the crowd responds with derision, underscoring a tense, skeptical mood in the town.

Shortly after the meeting, Murger is run down by an unseen driver in a car, leaving his death shrouded in mystery. The incident deepens the sense that the situation is growing more dangerous.

Julie is assaulted by a group of local thugs, an attack that Agar interrupts when he returns. The confrontation heightens the danger around the investigation and foreshadows the town's complicity.

Neil searches Murger's home and discovers a secret room with sexual paraphernalia. Murger's lover, Joe, reveals that Murger drove off with an unidentified woman before his death, complicating the mystery and hinting at hidden networks.

Herb Kline dies of a thrombosis during an intimate encounter with Dr. Susan Harris. Harris returns home with unsettling hints of what she really is, showing black compound eyes that suggest an insect-like nature.

Neil learns that Harris is transforming women into Bee Girls through cocooning and radiation. Nora, Kline's wife, is targeted and placed into the transformation cocoon, beginning her metamorphosis.

The next morning, Kline's body is discovered, and Captain Peters informs Nora. She immediately attempts to seduce him, illustrating the pervasive threat posed by the mutated women.

Armed with new evidence, Neil convenes the remaining department chairs and presents a theory that links the deaths to a form of insect-like mutation driven by radiation. Stan Williams mocks the idea, while Aldo Ferrara is more receptive.

At Grubowsky's funeral, a gamma radiation detector reveals radiation from the women in attendance who have undergone the treatment. The transformed women begin moving to eliminate the scientists, signaling the scope of the threat.

The transformed women mount an attack on the remaining scientists. Williams is nearly killed by his mutated wife, and Ferrara dies during a visit by Dr. Harris, who then lures Julie toward a lab transformation.

Neil finds Ferrara's body and rushes to Harris's lab, where the transformation of Julie has begun. Harris threatens to kill Julie unless Neil leaves, but he shoots the machinery, rescues Julie, and traps the mutated women inside as the lab explodes.
