The plot is centered around a colossal blast of heavily chilled mesosphere air, spreading over the Earth after a solar eclipse combined with the effects of environmental pollution caused a hole in the ozone layer. The catastrophic event threatens to engulf the entire world in ice. As Hobart, Tasmania, is hit by the cold front with temperatures of below -70 degrees Fahrenheit, causing people to die almost instantaneously, physicist Jack Tait (Michael Shanks) tries to find a solution while protecting his family.
The film was shot in Tasmania. The executive producer is Antony I. Ginnane, whose venture IFM/Filmways was responsible for the film release in Australia and New Zealand. The other executive producers are Tom Berry and Pierre David.
