When cattle mysteriously start dying of anthrax in a small Alberta ranching community, an RCMP officer tries to keep the peace as ranchers lay the blame on a local agricultural research center. A reporter encourages the angry ranchers - led by the Mounties mother-in-law - to stage a sit-in at the research center. When an eccentric old rancher dies after being exposed to a deadly strain of anthrax, the protesters are quarantined. No one notices that the reporter has disappeared - along with several vials of the deadly bacteria. The RCMP officer begins his own investigation, gleaning information from a U.S. government agent. He finds himself racing against time to recover the stolen anthrax.
