Atonement.

I love this film. It's perfect, just like the book from which is taken.
It's intense, passionate but painful.
 
On a fateful day, a young girl (who aspires to be a writer) makes a terrible mistake that has life-changing effects for many people. Consequently, she lives seeking atonement—which leads to an exploration on the nature of writing.
 
'I will return.
Find you.
Love you.
Marry you.
And live withiout shame.'
