At a lavish dinner party, a young biology professor fights for her sanity and her life after becoming convinced that her colleagues are being transformed into terrifying insect hybrids by their host, a jealous rival.  

SYNOPSIS:

In the Exterminator, mentally disturbed assistant professor Beth Dykowski is convinced that a senior colleague in the University Department of Biology, Maynard Winnow, has been stealing key formulas involved in her revolutionary research splicing human and insect genes.

At a dinner party hosted by Maynard, supposedly welcoming Beth back into the departmental fold after a brief psychiatric hospitalization for “paranoia”, Beth becomes convinced that Maynard has somehow treated his other guests, including her own husband, with her gene-splicing formula, turning them slowly into grotesque insect hybrids. In fact, Maynard’s behavior and comments at the party seem geared to amplifying Beth’s fears.

As guests are separated in smaller groups in Maynard’s bizarrely decorated manse, Beth lashes out at isolated individuals that she perceives to be transforming into various horrific bug hybrids. Eventually, she confronts Maynard who even further encourages her breakdown by acknowledging indirectly that he may have indeed done as Beth suspects, and a terrible fight to the bitter death ensues between them.

Beth barely prevails, but from her point of view, not in time enough to save the last few guests, including her husband from transforming. Believing she is fighting for her life, she violently dispatches of all them before they can do the same to her.

In the end, a swarm of cops arrive at the manse to find Beth alone, injured and bleeding in the front yard, ranting about the insect hybrids inside and what she has been forced to do. Inside the house, the cops discover the corpses of several brutalized guests whose bodies otherwise appear normal!

But as Beth is transported to the hospital in a police ambulance, one more horrific transformation takes place, finally answering the question as to whether Beth has lost her mind or has been witness to the most horrible of truths…
