Will (Ben Foster) and his daughter Tom (Thomasin McKenzie) live a life of dependence on each other. The father and daughter set up camp in the deep mountains and old forests, always living in isolation and without contact with modern society. Although the living conditions in the jungle are very bad, Will feels that this is the life they should have. One day, government staff found the father and daughter and forced them back to the civilized world. Although they were well fed and warmly dressed here, Will still felt as if he was in prison. Finally, he decided to take Tom back to his wild kingdom again, but Tom at this time was obviously more willing to stay in the city where everything was very convenient, and there was a huge disagreement between the father and daughter. Between his own wishes and his daughter's desires, how will Will choose?
