One night Sophie was taken away by a giant. She was carried to Giant Country. When she got there, she figured out that the giant who had taken her was the BFG or the Big Friendly Giant. He trapped dreams and blew them through a trumpet looking thing to sleeping children. The problem was that he was the only nice giant in Giant Country. All the other giants went out at night and ate children. Can the BFG and Sophie think of a plan to stop the giants from eating the children?
