I can't remember the year it came out but it is in color and definitely not something from the 90s and the language is English.
It starts out with a field, I think it was burned down, and a man is walking when he meets two guards and they ask for money for letting him go.
He was an outsider (from outside the Kingdom). He gave them a coin, and then killed them and took their money.
He enters some land where other tribes live, or perhaps outsiders.
He sees a pot with food and starts eating. He then gets knocked out by 2-3 guys. When he wakes up, his hands are tied. It is nighttime and he can hear a woman's and a man's voice. They are about to rape a woman in front of her father when he gets out of the rope and kills them.
I believe now some guards come and ask them and starts to make trouble (one of them is the son of the King). The man then kills the guards and ask the King's son to choose between death or cutting his own eye out. The King's son then cuts out his own eye but then the man gives him a message to deliver to his father the King.
The movie ends with you understanding that the man is, in fact, the Kings brother and he betrayed him and sold his son to be a slave.
