When teenage students kidnap Jan Hale they do not mean her any real harm - they just want enough ransom money from her husband Mark to afford a life of luxury. However, when they leave Jan handcuffed to the steering wheel of their car in the freezing cold, they are not aware that she suffers from a potentially fatal heart condition. Mark is racing against time as he and the police play a game of cat and mouse with the kidnappers, aware that he may never see his wife alive again.
