This Canadian nailbiter was originally sent out under the title The Plague. Both titles are appropos: the plague is M3, aka the Gemini Strain, aka a deadly virus. Released accidentally, M3 cuts a swath of death and disease around the world. Scientist Daniel Pilon races against time to develop an antidote. The flawless performances of Pilon and his costar Kate Reid more than compensate for The Plague's lack of production polish. ~ Hal Erickson, All Movie Guide
