So far in his life, Gabriel - selfish, arrogant and happy to be so - has only ever thought about two things: money and himself. When he's diagnosed with a terminal brain tumour, he doesn't see why anything should change.
But as the tumour grows, something strange starts happening. Whether Gabriel likes it or not, he's becoming . . . nicer. Kinder. A better person.
And then he meets Caitlin. Before, he wouldn't even have glanced at her; now he's entranced. But real change takes time - and time is something Gabriel just doesn't have.
As each day brings him closer to his last, has the one opportunity for a second chance passed him by?
