影片簡介：
湯姆一直過著沉悶無趣的生活，直到他懷著一顆不可救藥的浪漫的心，遇到了生命中的真愛——莎莫。即使是在這樣一個憤世嫉俗的現代社會裡，湯姆仍然堅定地相信著這個世界上存在著那種命中注定、非你不可、有如電光火石般燦爛的愛情，但他深愛的那個名叫莎莫的美麗女孩，對此卻持一種全然否定的態度。即使擁有著完全不一樣的愛情觀，卻不能阻止湯姆毫不氣餒地不斷追求莎莫，就像是現代版本的唐吉訶德，擁有著無限的能量和勇氣——可遺憾的是，莎莫最終還是離開了湯姆。
當湯姆仔細地回想這段維繫了500天的「真愛」時，突然之間，他意識到自己愛上的不只是一位可愛、幽默、智慧的女性……原來他愛上的是莎莫在他心中的倒影，並非某一個人，而是一種對愛情的理解和念想。於是湯姆在那500天的記憶和閃回畫面中不斷地遊弋、尋找，想要拼湊出愛情最初的模樣。

精彩片段對白：
S: Hey, Tom. I thought I might see you here. I always loved this place, ever since you brought me.
T: So, I, uh-- I guess I should say congratuations.
S: Only if you mean it.
T: Ah. Well, in that case--
S: So, are you okay?
T: I will be, eventually. You wanna--
S: Hmm. I like your suit.
T: Ah, thanks.
S: You look sharp.
T: [Laughs]So do you.
S: [Chuckles]Thanks.
T: I quit the office.
S: You did? I didn't know. That's great!
T: And you, um-- you're married.
S: Yeah. It's crazy, huh?
T: You should have told me when we were at the--
S: I know.
T: You know, at the wedding when we were dancing.
S: Well, he hadn't asked me yet.
T: But he was in your life.
S: Yeah.
T: So why'd you dance with me?
S: 'Cause I wanted to.
T: You just do what you want, don't you? You never wanted to be anybody's girlfriend, and now you're somebody's wife.
S: Surprised me too.
T: I don't think I'll ever understand that. I mean, it doesn't make sense.
S: It just happened.
T: Right, but that's what I don't understand. What just happened?
S: I just-- I just woke up one day, and I knew.
T: Knew what?
S: What I was never sure of with you.
T: You know what sucks? Realizing that everything you believe in is complete and utter bullshit. It sucks.
S: What do you mean?
T: Uh, you know, destiny, and soul mates, and true love, and all that childhood fairy tale nonsense. You were right. I-I should have listened to you.
S: No.
T: Yeah. What? What are you smiling at?
S: Tom.
T: What? What are you looking at me like that for?
S: Well, you know, I guess it's 'cause... I was sitting in a deli and reading Dorian Gray and... a guy comes up to me and... asked me about it, and... now he's my husband.
T: Yeah. And... so?
S: So, what if I'd gone to the movies? What if I had gone somewhere else for lunch? What if I'd gotten there 10 minutes later? It was-- It was meant to be. And I just kept thinking, Tom was right.
T: No.
S: Yeah, I did. [Laughs] I did. It just wasn't me that you were right about. I should go. But I'm really happy to see that you're doing well.
T: Summer! I really do hope that you're happy.
