Erin's wry wit and unfiltered frankness charm newly single Garrett over beer, bar trivia and breakfast the next morning. Their chemistry sparks a full-fledged summer fling, but neither expects it to last once Erin heads home to San Francisco and Garrett stays behind for his job in New York City. Yet, neither is sure they want it to end. Meanwhile, Garrett's friends don't like losing their best drinking buddy to yet another rocky romance, and Erin's high-strung, overprotective married sister, Corrine, wants to keep Erin from heading down an all-too-familiar road. But, despite the opposite coasts, the nay-saying friends and family, and a few unexpected temptations, the couple just might actually go the distance.
