The setting takes place in a world where chocolate and other fun things in life are illegal. Media and propaganda vehicles take the message of eating healthy to your home and streets. Much of the technology featured in Chocolate Underground is a blur between the past, present, and future. Trucks that transform into mechs and ways of detecting chocolate are just some of the future aspects. Yet it has normal television sets and helicopters. All this to enforce the law of selling, producing, and eating of chocolate and other naughty things like fireworks. Chocolate soymilk is healthy, why must they ban that? The two boys Huntley and Smudger aren’t fans of these laws, which will bring them into the illegal practice of secretly helping people get chocolate.

Huntly = hunt and Smudger = smuggler?

Each episode is short because the anime is an ONA, anime that originally airs on the Internet. Chocolate Underground is lightly based on the British novel called Bootleg by Alex Shearer. For an anime not aired on television or in theaters the animation is pretty good. The start shows how seriously these laws are taken, even for something so little. Personal property means very little.
