Senior high student Ёжик studies at a science lyceum and gets sent on summer practice to the Institute of Bioengineering and the Gene’s Biology, where unique properties of were-animal creatures are studied for the benefit of humanity. Ёжик and his friends accidentally discover that one of these experimental animals—Samson the bear—is intelligent. Samson is the institute’s most valuable specimen. He was brought from faraway Vancouver, where researchers in a local laboratory studied training wereanimals to speak. While living in captivity, all the animals the kids study suffer, but freeing them is practically impossible: 24/7 surveillance is kept on the subjects, and the institute runs on a pass system. Ёжику has to answer a serious question: what matters more—scientific progress or compassion for a living being?
