Columnist and author Femke Boot (Katja Herbers) rails against the online discourse which includes countless disturbing attacks against her and her daughter Anna. The police dismisses her. She's struggling to write her next book. She spots nasty racist misogynist tweets apparently coming from her noisy neighbor. She goes on a murderous revenge rampage.

This is fine. I am most intrigued with Katja acting in her native tongue. She sounds like I expected. A more compelling story would have somebody else catfishing as the noisy neighbor. She kills an innocent and gets blackmailed for it. That's a good twist. Some of these people must be using burner accounts. It's trolling 101. It's too easy to track down these people and I don't believe that Femke can kill these men with her hands. I do like the freedom of speech argument. This is fine.
