The movie is about human girl befriends from an orphan, a benevolent giant, hail as the "Huge Friendly Giant", who brings her to Huge Country, where they tried to halt man-eating goliath that are attacking the human world. Sophie is the orphaned young girl that resides in an orphanage in London. One late sunset, she awakens and looks outside the window, where she saw an aged-looking giant. The Goliath detains her and brings her into the Giant Country. There, he clarifies that Sophie should stay with him throughout her life since she saw him and is not being allowed to say to anyone that there are still giants. The giant presented himself being the BFG or "Big Friendly Giant". That evening, the BFG causes her a nightmare because she tries to escape, and she saw something about being eaten by an even more massive giant in her dreams.
BFG then clarifies that he can hold dreams. BFG places Sophie in the tree house and begins working with his dreams. Sophie finally encouraged the BFG to bring her to the Dream Country. But initially, they should pass Fleshlumpeater and the other man-eating giants Bonecruncher, Manhugger, Meatdripper, Butcher Boy, Maidmasher, Gizzardgulper, Bloodbottler, and Childchewer, who are all sleeping. They unintentionally awaken up the man-eating monster that decides to intimidate BFG and fight a game with BFG. Sophie barely avoids their discovery, but by mistake drops her blanket. Finally, the pair runs away after the thunderstorm. Sophie told BFG that he must not permit other giants to oppress him. Meanwhile, the other giants saw Sophie's blanket and search to look out for her.
The movie message is somewhat screwed up. When BFG decided to return the child back in the orphanage for the little girl security, she then tosses herself into the window and believed that BFG will grab her. That works out impressive for her, but what about those little impressionable kids viewing the film? And at the final touch, it is exposed that BFG can really hear the murmur of kids everywhere. The trailer can convince you that the movie is an animated film, but the actual film was not, since there are disturbing mixtures of actual child into the CGI world of giants.
