1941. War is raging.

And Joseph has been sent to live in the city, where bombers rule the skies. There, he will live with Mrs F, a gruff woman with no fondness for children. Her only loves are the rundown zoo she owns and its mighty silverback gorilla, Adonis.

As the weeks pass, Joseph and Adonis become friends, but what will happen when the bombers set him rampaging free?
