Sanningen enligt Hassan Zubier

Hassan Zubier became a hero in the most unlikely of circumstances, in Finland's first act of Islamic terrorism with a jihadist purpose. But heroism quickly faded as Zubier found it difficult to stick to the truth. Now he wants to clear his name and decides to tell all to journalist-writer Matilda Gyllenberg, who plans to write a book about him.

When Matilda tries to depict Hassan's life in a book, she is not satisfied with his version of the events. She takes a deep dive into Hassan's background and discovers a life story that does not match his narrative. The deeper Matilda delves, the clearer the picture becomes of a man who has created an alternative reality for himself because the truth is too hard to bear. Hassan has been hiding behind a wall of lies for 20 years, but the aftermath of Turku terrorist attack breaks down that wall.

Hassan returns to Turku to defend against the fraud charges against him. At the same time, Matilda discovers sensitive information about his infant daughter - information of which Hassan himself has been unaware. When Matilda presents the new information to Hassan, the whole partnership is put at stake. Matilda doesn't want to publish a book that doesn't tell the whole truth, but Hassan feels the price of publishing the book is too high.
