From the director of Prisoners and Enemy comes this searing drama based on true events. In December, 1989, a disturbed killer stalked the campus of Montreal Polytechnique with one goal in mind - to target as many young women as possible.
After massive tidal waves strike the American East Coast, a team of scientists confers to discover the reason behind the devastating phenomenon. Among them is nuclear arms expert John McAdams and scientist Sophie Marleau who believe that the cataclysms are terrorist-triggered undersea missiles. But when McAdams himself becomes the prime suspect, he and Sophie must outrun the feds and unmask the real madman before he strikes again.
