Seagal's first direct-to-video film, it features him as a local doctor and former immunologist who races against time to find a cure for an active viral outbreak, the origins of which trace back to a militia leader who injected himself with a deadly virus.
Near the town of Ennis, Montana, local doctor and former government research immunologist Wesley McClaren who has an interest in herbal medicine and is also a weapons and self-defense expert, is called to a hospital when people start dying from an unknown but very deadly disease.
He determines that the cause is a highly dangerous airborne virus and calls in a Biological Response team, who seal off the town while doctors start treating sufferers with a vaccine.
The source of the virus is traced to a local self-styled rebel militia leader, Floyd Chisholm, who has given himself up after a long siege and has been arrested on weapons charges.
Wesley finds out why Ann and Holly are not being affected by the virus: they have been drinking tea made with a specific wild herb that is known to Native American healers.
As soon as the biological protection team learn of the cure, they go out and pick all the flowers they can find and drop them by helicopter over the town, telling the people to boil them and drink the liquid.
