Olsen Bandens Sidste Plan [The Olsen Gang's Last Plan]

Vridsløselille is about to be torn down, but everything is still standing as when it was abandoned. No one has touched anything since the last prisoners left the place. Maybe there is something hidden in Egon Olsen's old cell that will make the lucky finder stinking rich? Rumor has it that he has hidden a plan to break into a hidden safe that should be in the old warden's office. The safe contains a red folder filled with DKK 5 million. Your task is to find the plan and the money before the prison is demolished and they are lost forever!
