Thelma and Tico receive a new and exciting assignment from the Bureau of Non-Events (BNE) – a super-secret bureau that monitors and fights supernatural forces. An eccentric multibillionaire has been buying up huge land areas for decades, and the area is under strict supervision. No one is allowed on the inside of the ten meter-tall electrical fencing – and not many people want to try either as the area is surrounded by mines and armed guards. Airplanes are redirected around the area, drones trying to spy are being shot down. Thelma and Tico must reveal the secrets behind the tall fences, but what they find is not only surprising, it is potentially life threatening.
