When her soon-to-be-married little sister and fiancé become marooned at a mountain retreat days before their wedding, Amelia and the best man, Grayson Tanner, are tasked with stepping in to save the wedding.

Amelia Hart is a florist who does celebrity weddings in the United States, but she dreams of owning a flower shop. Her sister Bonnie is about to be married in Australia, and Amelia is the maid of honor. Unfortunately, Bonnie and her fiancé Jake get marooned at a retreat days before the wedding. This means that Amelia and the best man, Grayson Tanner, have to take care of all the wedding preparations. Grayson works as a veterinarian in Australia. At first, Amelia and Grayson don't get along. However, while choosing entertainment, making floral arrangements, taking dance lessons, hanging out together, and talking about their lives, the two start falling for each other. The problem is that Amelia has to go back to her job in the US when the wedding is over, making a future with Grayson unlikely.—Patrick Lin
