Ollantay is the best general of the Inca Pachacuti.
Despite his merits, Ollantay is of plebeian origin, so when he falls in love with the Inca's daughter, Cusi Coyllur, he has to keep the relationship secret. The laws of the time prohibit aristocracy and plebeians from getting married.
However, Ollantay tries to convince the father of his beloved. When he finds out about the relationship, he gets angry. From there, Ollantay flees to Antisuyo and rebels against the ruler.
