How far would you go for someone you love? Nobel Prize-winning scientist Sarah Collier has taken a step back from work to spend more time with her family. Her father's suffering from Alzheimer's and needs special care. Sarah has started to show tell-tale signs of the disease too. She's been experiencing blackouts and memory loss. It's early days but she must face the possibility that she won't be there to see her daughter grow up. Daniel, her husband, a neuroscientist himself, is doing his best to be supportive but she already knows that she will have to be the strong one. For all of them. So when Sarah is invited to be the guest of honour at a prestigious biotech conference in Geneva she declines, wanting to stay out of the public eye - that is until Daniel shows her the kind of work that the enigmatic Mauritz Schiller has been developing.
