When the last season of a show is approaching, fans have a lot of theories and questions about what's going to happen. For the upcoming final season of "Money Heist", one of Netflix's most popular shows, people from all over the world had questions.

Then, in a shocking twist, the campaign also created 30 billboards with answers. It was up to the public to go on their own quest, trying to match up each question with the correct answer.
