An outbreak of a bacteria called M-3 causes people to die in extreme pain via body spasms. A woman who is a carrier escapes from a hospital and goes on the run, spreading the plague to people she encounters, and onto food in fast food stops etc. She has no idea however that she is a carrier, and as such may carry a cure.
