[1] A psychiatrist informs the mother (Marilyn Adams) of young Dornwinkle (Kris Russell) that he is a genius, but has the potential for madness and that with proper nurturing, he will be fine.

After escaping from the hospital, Dornwinkle is hired as a substitute high school physics teacher under the pseudonym, Dr. Kevin Smith.

This event, combined with the side effects of the invisibility serum, puts him over the edge and sends him on a killing spree.

Now invisible, he kills Bubba (Eric Champnella) with a sandwich and Betty (Debra Lamb) with a fire hose.

Next, he kills Joan (Kalei Shallabarger) by drowning her in a fish tank and strangles April (Gail Lyon).

He then proceeds to kill Vicky (Shannon Wilsey) in the girls shower by throwing a radio into the water, electrocuting her, while Gordon (Rod Sweitzer) waits outside.
