This is a story about how low politicians will go to achieve success. It's brought out time and time again within the political intrigues in the film, which were very predictable and therefore boring as far as political "thrillers" go.
What is left completely unexplained for no good reason is, however, easy enough to figure out, again within the context of corrupt politicians - Marina as a small child saw her father's crime, was locked away and subjected to years of therapy to force her to forget what she saw and make her crazy in the process, and her birth certificate was changed to make her younger so she wasn't even present during the time of the murder - unless you want to go with some supernatural event, which just makes no sense within the central theme.
Why Marina's story wasn't shown or explained as explicitly as the events in the rest of the film is beyond me, but that's for the producers to explain, unless that's some supernatural event also..
