This is a TV-level or TV-like "drama in family" movie about Iris Boelens, a young single mother and lawyer, contending with an autistic child and the discovery that she has a brother who is locked up for a double murder --and who has autism also. Not much action (violence) or action related suspense in this movie. It is mainly psychological drama and suspense (thriller, I guess) that originates from this lawyer's dogged search for the truth about her brother and family and the people who want to stop her when she decides to investigate his crime and get him new representation.
Whether or not you warm to this movie depends on whether or not you care about the central character in it and/or the subject matter. Therefore, whether or not you are sympathetic to Iris Boelens and the problems and mystery of her family. Iris is a busy woman, juggling a demanding job and problem child who has been suspended from school. Her mother has a cool, no-nonsense facade but one has a sense that deep down she perhaps cares. She is taciturn; doesn't want to give Iris any info about her newly discovered brother. This leaves Iris no choice but to turn to her trusty computer and perhaps the Dutch version of Google. The movie grows on you if you're patient and has an interesting ending that actually made me say "Sh!t, I didn't see that coming". Love, Boloxxxi.
