Since we have no details about the 'barat short film story', we can only guess. Maybe there's a young Barat who is the protagonist and he has an older friend who guides him through some difficult situations. Or perhaps there's a group of characters in Barat's village or town, and they all contribute to the story in different ways.
I don't know as there's no information given. It could be Barat himself if he's a character, or it might be his family and friends.
Without seeing the short film, it's impossible to tell for sure. However, if it's named after a person, Barat could be the main character. There might also be other supporting characters like a love interest, a mentor, or an antagonist that play important roles in the story.
