Sophie, a ten year old orphaned girl who lives in a London orphanage stays awake reading through the nights due to her insomnia. At 3:00 AM, or what she calls the “witching hour“, she sees an elderly giant outside her window. The giant captures her and takes her into Giant Country. There, he explains that he named himself the “Big Friendly Giant” or the “BFG” for short and that Sophie must stay with him for the rest of her life because she saw him and must not be allowed to reveal the existence of giants. After learning that she has insomnia and that she doesn’t believe he can control dreams, he manages to read her to sleep and gives her a nightmare about failing to escape and being eaten by another giant.
