Skyros (The Island)

Katerina is a 38-year-old lady who lives in Athens, Greece and works as a journalist, in a radio station. She is from Skyros, a Greek island in the north part of Aegean Sea.
When she was 22 she got pregnant by a German tourist who left and never learnt for this child. Katerina's mother, Mrs Gianna was ashamed of it because in a small island like this, this new would be the biggest gossip. So, she decided to force Katerina to get married to Stelios who was a much older man who really wanted to marry someone, no matter what. Katerina did it because she didn't want to make her mother sadder than she was.
Katerina gave birth but the baby died in a year. Heartbroken as she was, she wanted to break up with Stelios but he wouldn't give her a divorce....

After seven years of a hellish marriage, Stelios was found drawn in the port of Atsitsa (in Skyros). How will Katerina get away with it when everyone thinks that she killed him?
What would be the role of her brother Argiris?
