Masks Inc. is a cosmetics company that makes beauty products. It uses whale oil from dead whales only and does not kill whales to obtain blubber. A newspaper publishes a report stating that Masks Inc. allegedly hires poachers to hunt and slaughter blue whales for oil. This enrages animal rights activists, and they stage protests against Masks Inc. and demand that its products be banned from the market.
