Having agreed to submit to a genetic research project headed by Dr. Paul Flynn (Lane Smith), cancer victim Cindy Oliver (Kate Linder) leaves Flynn's hospital--and promptly dies. Soon thereafter, several other people who'd come in contact with Cindy also turn up dead. Investigating, Quincy (Jack Klugman) comes to the sobering conclusion that Dr. Flynn's experimental cancer-cure serum has spawned a mutant respiratory virus--which is not only fatal, but may also be unstoppable.
