This movie starts off with the main character as a bad guy (he was either a former war assassin or something like that). He gets found by a girl in a body of water I believe. He pretends to be someone...

What I remember about the movie is that it has a tree in its cover and a type of tree in its title. Its a romance/drama movie. I only saw it once and it has the male and the female in like a prison type...
