(There are Spoilers) End of the human race via a deadly and unstoppable infectious disease or virus is the storyline of the the made for TV thriller "Carriers".
Were told that a US military/industrial operation for the US Army involving the drug company Gensystems got involved in a top-secret biological research experiment that suddenly went berserk when it. The by-product of the experiment, was introduced to the public as a fertility drug. One of the scientists working on this drug Jonathon Parker, Berry Bell, unwitting gave it to his wife Holly, Pamala Reed, to increase her chances of getting pregnant who eventually gave birth to twins two normal and healthy girls Alex & Lucy, Elke Larson & Kylie Larson, who were born with the virus in their systems. It was much later when they were in Gabon Africa with their father at the Gensystems Camp Rafflesla Research Facility that all hell broke loose when the two girls accidentally ate these genetically grown green barriers that brought the dormant and deadly virus out into the open.
Spreading across the Atlantic after wiping out the entire Camp Rafflesla staff, except Lucy & Alex, the virus enters the US through a shipment of monkeys slated to be used for experimental purposes at Ft. Detrick MD. Within days it kills dozens of persons who as much as came in contact with either the monkeys or persons or were infected, by being bitten or sneezed at, by them.
The movie gets a bit complicated when Doctor Maj. Carman Travis, Judith Light, and her colleague at Ft. Detrick Capt. Arends, Bill Nunn, start to uncover what's behind all these deaths. With the help of an unknown worker at Gensystems they come up with a government plan to use biological warfare against an enemy country by infecting It's people with the deadly drug. The plan was to sneak the drug into country as green berries and then have the virus activated by's it's population eating them.
As both Maj. Travis & Capt. Arends get closer to the truth they find where the experiment were being conducted at a closed down US Army installation in Mississippi called Ft. Willard. Capt. Arends finding a secret CD disk in the forts computer room he later comes in contact with one of the persons who was very much involved in the experiments a former worker for Gensystems Dr. Larrimore, Joe Insoe. Dr. Larrimore reluctantly, when he realized that millions of lives are at stake, reveals the whole truth behind the experiments at the fort and who was behind them.
Maj. Travis desperately trying to get a antidote, from the two carriers Alex & Lucy, made and immediately used to inoculate the American public from the virus is stymied by her boss Col.John O. Bailey, Philip Bosso. Unknown to Maj.Travis was involved with the covert experiments at Ft. Willard with Gensystems some ten years ago. Col Bailey will do anything, even murder, to keep the truth form coming out about his and the US military and the president of Gensystems Frank Sanborn (Nicholas Pryor), who had earlier committed suicide, involvement in them.
Nail biting but predictable ending with Maj. Travis and Col. Bailey, Maj. Travis superior, facing off as the two sergeants under Col. Bailey's command are left with the unenviable dilemma of arresting Maj. Travis thus letting the entire country go to hell. The solders are thus faced with having hundreds of thousands if not millions of Americans die from this deadly and uncountable virus, in following their commanding officers Col. Bailey orders. Or using their common sense and rejecting Col. Bailey and letting Maj. Travis gets the very important antidote out, in the little time that she has left, to the American public in order to save them. You can just guess what their decision was.
