Az elefánt (1978)

Just a few days before the foreign delegation arrives at the ZOO, someone overnight scribbled Jumbo, the precious elephant with unwashable paint. There are writing on both sides, critical words about the ZOO and it's director himself. The retiring police with the help of a graphologist determine during the investigation that the crime was committed be the elephant's former care assistant, who resigned a few days ago because of his replacement to the insect house. The delegation coming soon, they have to present their pride, the elephant, but not even the former carer knows how to remove the paint.
