Canada
A research program abandoned by the best solar physicist when the Pentagon wanted to put it to military use has been resumed by his former deputy. Her incompetence and the Defense secretary's haste cause it to be tested too soon, stirring unprecedented solar flares, ultimately a plasma causing disasters on all continents. Only the genius can think of a way out, only to be victimized by the secretary, who needs to cover up. Even when it turns out the earth's core has stopped spinning, spelling an unimaginable seismic apocalypse, the genius must still evade special forces to stay free and save the world again. - IMDb
