Where can I watch Das Verschwinden in Belgium?

20-year-old Janine Grabowski disappears in a small Bavarian town near the Czech border. While all evidence indicates that Janine secretly wanted to leave the backcountry, her mother, Michelle, becomes increasingly convinced that there's something amiss. Michelle's missing person's report is quickly filed away by the police. So the single mother is forced to investigate at her own risk. The longer she hunts for an answer to Janine's disappearance, the more she discovers about her daughter and the people with whom she kept company. She begins to doubt whether Janine even wants to be found.
