A film without sound about Gust the gorilla - one of the best known animals from the Antwerp Zoo - and his keeper Samson. We follow a day in the life of the young Gust, who only recently arrived in the zoo. The playful gorilla is washed and taken care of, undergoes a medical test and during playtime meets up with two lion cubs and a teddy beer. This is followed by a walk through the zoo among the interested visitors. The film is accompanied on the piano by Hughes Maréchal.
