When his girlfriend, Summer (Zooey Deschanel), unceremoniously dumps him, greeting-card copywriter and hopeless romantic Tom (Golden Globe nominee Joseph Gordon-Levitt) begins sifting through the year-plus worth of days they spent together, looking for clues to what went awry. As he recalls the good and bad times he spent with the commitment-phobic girl, his heart reawakens to what it cherishes most. Marc Webb directs this uncommon love story.
