When Ava Green turns twenty-eight, she discovers this will be her last birthday. The cancer she thought she'd beaten three years ago is back, only this time it's terminal. But she is not going to let the cancer define her last, precious months, she is going to make her childhood dream come true: her wedding. With no groom, no money and very little time, Ava's friends and family rally around her and decide they will help her throw the wedding of her dreams, just without the actual vows. A mammoth organisation begins.
As word spreads, people offer help. In an uncertain time, the whole country seizes the story of a woman whose dying wish is simple, and they unite to give her a wedding to remember. But when a photographer called James Gable arrives to document the whole event, it becomes painfully clear that it's never too late to discover the love of your life.
