A girl who doesn't believe true love exists... and a boy who falls for her... this is not a love story, yet an offbeat story about love. It's about a phase in a boy's life, the first 250 days of which make his world beautiful and the next 250 makes it messy, all because of a girl, Summer Finn. That's 500 Days of Summer for you!

We all struggle at times with what to say and how to say it. More accurately, we struggle with how to express our feelings and with the considerations of how the person we love will interpret what we say. True love, commitment, ongoing effort... are all needed, but the adventure starts before any of those are established.
