"The Boxtrolls" is a comedic fable that unfolds in Cheesebridge, a posh Victorian-era town obsessed with wealth, class, and the stinkiest of fine cheeses. Beneath its charming cobblestone streets dwell the Boxtrolls, foul monsters who crawl out of the sewers at night and steal what the townspeople hold most dear: their children and their cheeses. At least, that's the legend residents have always believed. In truth, the Boxtrolls are an underground cavern-dwelling community of quirky and lovable oddballs who wear recycled cardboard boxes the way turtles wear their shells. The Boxtrolls have raised an orphaned human boy, Eggs (voiced by Hempstead-Wright), since infancy as one of their dumpster-diving and mechanical junk-collecting own. When the Boxtrolls are targeted by villainous pest exterminator Archibald Snatcher (Kingsley), who is bent on eradicating them as his ticket to Cheesebridge society, the kindhearted band of tinkerers must turn to their adopted charge and adventurous rich girl Winnie (Fanning) to bridge two worlds amidst the winds of change - and cheese.
