Orphan Lena hasn't been too happy. Her foster parents only see the eleven-year-old as a pay check. But one day, Lena finds a huge gorilla at the doorstep: It is Benedict, her last remaining relative. He has the papers to prove it. A wonderful life begins for the two as they move in together. And even though Benedict can't talk, he sure can read and write. But there are problems: Lena's old foster parents hatch a plan to get her and her money back. Yes, Benedict is a gorilla - but they belong together, and everybody needs to deal with that.
