The series centers on two inseparable yet very different brothers, the Venturas. One is named Dean, the other Hank. It’s amazing how such teenagers manage to get into so many different troubles in such a short time. Dean is a very good guy, calm, gentle, polite with people and careful in his interactions, trying not to offend or hurt their feelings. At the same time Hank is the complete opposite: he’s not at all inclined to be formal with people, very active, full of energy, and he’s always trying to channel it somewhere, coming up with all sorts of schemes. He often drags his brother along, who doesn’t particularly mind. Besides them, the main character is their father, Dr. Ventura. He is the son of another brilliant inventor. Dr. Ventura occasionally sells the inventions created by his father, and they live on that money. But that doesn’t mean he squanders money; as a capable inventor and scientist himself, he has achieved significant advances in cloning. He creates robots, which immediately find demand among various criminal outfits. From that moment, he must protect himself and his family from bandit raids.
