Walter Mitty is a long-term single who worked as Manager of the Photograph Department in Life magazine, he spent his entire life keeping the negative film and enjoyed his job, no less and no more. He often imagines another story of his life that he never had, sometimes he imagines the other side of himself that he wanted. Everything is gonna be awesome in his head, never spoken or happen. He kept his mind inside. (Actually, he is liking the new girl, but he tried to communicate only wink in her profile).

Then, a new director came and screwed up, he decided to close the magazine. off course it's affected the whole company, almost all would be jobless. But they're still prepared for the last edition of Life magazine, one of their photographers mentioned his masterpiece the negative 25 for the last cover. Mitty searched it in his whole office, but never found it, and confused. He tried to call the photographer (Sean) but as a nomad person, he had an inconsistent address.

1st photograph took him to Iceland (or Greenland), a strange place outside his dream which brought the wildest experience that he ever imagined. 

2nd photograph took him into the Vulcano, he risked his life by following Sean, but ... not this time ... he is late and Sean was gone.

3rd photograph took him to his mother's piano, it was a big surprise Sean ever came to his house.
