(500) Days of Summer is a romantic-drama-comedy film. After it looks as if she's left his life for good this time, Tom Hansen reflects back on the just over one year that he knew Summer Finn. Despite being physically average in almost every respect, Summer had always attracted the attention of men, Tom included.
For Tom, it was love at first sight when she walked into the greeting card company where he worked, she the new administrative assistant. Soon, Tom knew that Summer was the woman with whom he wanted to spend the rest of his life.
Although Summer did not believe in relationships or boyfriends - in her assertion, real life will always ultimately get in the way - Tom and Summer became more than just friends. Through the trials and tribulations of Tom and Summer's so-called relationship, Tom could always count on the advice of his two best friends, McKenzie and Paul.
However, it is Tom's adolescent sister, Rachel, who is his voice of reason. After all is said and done, Tom is the one who ultimately has to make the choice to listen or not.
He's Tom, from New Jersey, working in L.A. writing greeting cards even through he's an architect by training. She's Summer, in from Michigan. Day one is her first day as an AA in Tom's office. We jump back and forth in time: by day 67, they've become an item when she decides to put aside the lovemaking and just be friends.
Tom, a romantic who's sure Summer is the one for him, wallows in self pity. We go back to the early days and see the relationship begin. Summer tells him right away that she doesn't believe in love. He mopes well past day 100. Then, as day 500 approaches, they find themselves at a wedding together. Does the old flame rekindle? Is Tom right that destiny controls love?
