After returning home from her husband's funeral, widow Ellen is startled by two young burglars who sneak through her house. Furious, she calls 112, where operator Joyce lends a listening ear and tries to calm her down. Especially when Ellen wants to take matters into her own hands and defend herself and her beloved dog Amadeus with the help of a bat.

112 operator Lieke has to deal with a false report about a suspicious situation. Geert often calls from his apartment and clearly wants to fight his loneliness. She brushes it off, but moments later another disturbing message arrives at the same address.

When Jolanda finds her mother unconscious at the bottom of the stairs and her daughter is nowhere to be seen, she calls the emergency center in panic. While dispatcher Boudewijn does his best to understand the situation, Jolanda immediately starts talking about her suspicions against her husband Albert. With difficulty Boudewijn tries to struggle through her chaotic story and to steer the search in the right direction.
