In 1897 a fictional hill-top town of Cheesebridge, Norvenia during the Victorian era, rumors abound that subterranean trolls (known as Boxtrolls for the cardboard boxes they wear) have kidnapped a baby. Pest exterminator Archibald Snatcher strikes a deal with the city's leader Lord Portley-Rind to exterminate every Boxtroll in exchange for membership in the city's cheese-loving council called the White Hats, despite the fact that he is severely allergic to cheese. Snatcher hatches an evil plan and teams up with his three loyal advisors Mr. Trout, Mr. Pickles, and Mr. Gristle to kill the White Hats, exterminate the Boxtrolls, rule Cheesebridge, and rename it "Snatcher-ville".
