13th Street-The action and suspense channel

Found this on the CoolHunter- "To promote the exclusive thrillers and horror films on 13th Street, the toilet of a nightclub in Hamburg was specially prepared. Just after entering the room, the light suddenly goes out and the room is bathed in Black light. And now a bloody crime scene becomes visible on the floor and walls: "See what others don't see. 13TH STREET. The Action and Suspense Channel."
