The Boxtrolls movie plot

"Cheese Bridge" was a glamorous city during the Victorian era. The residents here were obsessed with wealth, rank, and stinky cheese! However, under their unique cobblestone roads live a group of "terrible" monsters. They crawl out of the sewer every night and steal the children and cheese from the residents' homes-of course, this is only a side word of the local residents! In fact, "The Boxtrolls" are a group of very cute and shy creatures. They hide in recyclable cardboard boxes, just like tortoises like to hide in their own shells. The Boxtrolls adopted a human orphan and named him "The Egg". The little boy and Winnie, an adventurous girl from the earthly world, became good friends. They needed to build a bridge between The Boxtrolls and humans—— Especially when human politicians portray The Boxtrolls as a group of terrible monsters for the sake of votes, and then incite the people to expel them.
