Maddie (Annabel Scholey) and Taylor (Hannah Arterton) are sisters, but they are nothing alike; vivacious and bright Maddie is in love with love, finding herself in the arms of this man and the other, while Taylor is reserved and timid, placing her academic life above romance. After a bad breakup, Maddie follows Taylor’s advice and goes to a small coastal village in Italy, where Taylor had once found romance, in order to find herself. When Taylor arrives a few weeks later, her sister drops a bomb: she’s getting married! Sure, she’s only known the guy for five weeks, but when you know, you know, right? Little does Maddie know that her beau, Raf (Giulio Berruti), is her little sister’s former holiday romance, maybe even the love of her life.
