A Family Reunited
As a blizzard descends from the north on Christmas Eve, several people converge on a remote family estate in Scotland. Stanley Oxenford, director of a pharmaceutical research company, has everything riding on a drug he is developing to fight a lethal virus.

A Brewing Storm
Several others are interested in his success too: his children, at home for Christmas with their offspring, have their eyes on the money he will make; Toni Gallo, forced to resign from the police department in disgrace, is betting her career on keeping the drug safe; and a local television reporter, determined to move up, has sniffed the story, even if he has to bend the facts to tell it.

A House Under Siege
A sinister gang spots an opportunity to use one of Stanley's children against him and steal the virus. As everyone takes shelter, it becomes apparent that being inside the house may be more dangerous than the storm outside, especially when a lethal virus might be on the loose . . .
