When Ben and Bea cross paths in a coffee shop during a bathroom issue, they are drawn to one another right away. Over grilled cheese and sex, they spend the evening together at Ben’s house. The next day, Bea leaves early and hears Ben playfully downplaying the intense episode with his friend Pete. A few months later, Ben’s sister Halle and Claudia’s sister Bea get engaged, which brings the lovers back together. Bea and Ben’s reunion gets stronger as they have to pretend to be pleasant to their parents and friends during an Australian destination wedding. The entrance of Bea’s ex-fiance Jonathan and Ben’s ex-girlfriend Margaret, however, throws the week for a loop while the rest of the group hopes that the rivaling visitors will stay friends. Their efforts to reconcile with their former spouses are disrupted when Bea and Ben choose to indulge their romantic tendencies and spend more time getting to know one another.
