Joseph Gordon-Levitt and Zooey Deschanel star in director Marc Webb's wry, nonlinear romantic comedy about a man who falls head over heels for a woman who doesn't believe in love. Mark (Gordon-Levitt) is an aspiring architect who currently earns his living as a greeting card writer. Upon encountering his boss' beautiful new secretary, Summer (Deschanel), Mark discovers that the pair have plenty in common despite the fact that she's seemingly out of his league; for starters, they both love the Smiths, and they're both fans of surrealist artist Magritte. Before long Mark is smitten. All he can think about is Summer. Mark believes deeply in the concept of soul mates, and he's finally found his. Unfortunately for Mark, Summer sees true love as the stuff of fairy tales, and isn't looking for romance. Undaunted and undeterred by his breezy lover's casual stance on relationships, Mark summons all of his might and courage to pursue Summer and convince her that their love is real.
