Young zookeeper Tim cycles through life seemingly carefree. He has a dream job as a gorilla caretaker and is head over heels in love with beautiful teacher Ellen. But behind the facade of this young happiness lies the story of Tim's broken family. A family whose connection with the ZOO goes back to the early 1990s in an okapire reserve in Congo. There, a tragedy occurred that has marked them for three generations and severely disrupted relations between them.
