Erin and Garrett are good together--even when they're apart. When aspiring journalist Erin (Drew Barrymore) moves to San Francisco to finish her last year of school, boyfriend Garrett (Justin Long), an assistant music scout, stays in Manhattan to pursue his ambitions and wait on that promotion he's been promised.
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. But when six weeks of romping through the city inadvertently become meaningful, neither is sure they want it to end.
