Samuel, Nadya, and Christian, three friends from working-class families, receive scholarships to study at the private school "Las Encinas," where the elite of society send their children. In the new school, the friends feel uncomfortable due to the difference in their families' incomes and become outcasts. However, the teenagers gradually show their worth and prove that they are no less than those with wealthy parents. At "Las Encinas," they make friends and enemies, fall in love and break up, and also come to understand the life of the elite, often far from decency and virtue.
