The story of two people who begin to fall in love as the world begins to fall apart.

Susan is a scientist. Michael is a chef. He takes a break from the kitchen heat in the alleyway below her apartment; she smokes a cigarette at the window above. He calls up for a light - the first spark in their passionate affair.

But the world is about to change dramatically. As love turns Susan and Michael's lives upside down, people across the globe begin to experience strange symptoms, which first affect the emotions then the senses, one by one.

Everything changes. But people laugh, they cry, they eat and drink, they go about their daily business. They adapt, they change, they cope, they live and they love - because life must go on. And so it does.
