Irina is also upset that no one in her family has read her recently released debut book.
The book depicts the difficulties of her growing up in rural Denmark. Half of the book is about Catrine — a girl who bullied Irina throughout school. And ironically, once she arrives, she finds out that her brother's maid is none other than Catrine.
Things go from bad to worse as Irina is systematically ostracised in favour of Catrine.
Her former friends have convenient memory lapses, Irina's mother has taken a shine to her future daughter-in-law and even promised to hand the flower shop over to her. Which is more overwhelming, she gave Catrine her grandma's wedding ring, Irina was supposed to get. Apart from everything, Catrine is a dominant type who wants everything under her control. She keeps her nasty side hidden from all but Laura, and thanks to her the family comes across the interview Irina has done for a TV program, in which she is explicit about who was responsible for her unhappy youth. As if this isn't enough, Irina also has to tolerate her
self-centred boyfriend, Benjamin, who arrives for the wedding in time to find fault with everyone, including her.
Persona Non Grata raises a number of questions. First of all it is about the bullying and ignoring the past. Irina indeed had a trauma because of being bullied throughout her childhood, but her family pretends not to remember this. Every time Irina raises the matter, everyone blows up at her, wanting her to keep quiet. The movie hints this is not the right way to behave, as because of the ignorance, things get even worse and lead to a big scandal and even a fight. It wouldn't happen if Irina's family just had a conversation with the girl, listened to her and apologized for the past, as it would give Irina an opportunity to finally let go of
the pain she held inside. Besides, the movie also reveals Catrine's tough story, showing us that childhood bullying doesn't come from nowhere.
