Is this text correct?

My favorite film is The Last of the Mohicans. It is directed by Michael Mann and is based on the historical novel by James Cooper.
It is set in eighteenth-century America during the Seven Years' War, in which France and England fought for control of what is now Canada and the northern United States. The French had the support of the tribe of the Hurons, while the Mohican tribe of Indians helped the British army.
In the film violent scenes of war are mixed with a beautiful love story between the protagonists.
What I like about the film is its soundtrack and the wonderful landscape that can be seen throughout the story. And what I dislike is when one of the Hurons cruelly kills the father of the protagonist, and pulls out his heart with his knife.
At the end of the film, the last of the Mohicans is left with the woman he was in love with. Meanwhile, her sister is captured by the tribe of the Hurons. So, she decides to commit suicide by jumping off a cliff vacuum ???.

Extremely well written! My corrections are in red and my suggestions to sound more natural are in blue/grey.

I'm not sure about the transalation of vacuum in this context. "Jumping of a cliff" is fine without any additional words, however you could also say "jumping off a cliff edge" (more commonly heard as "jumping off the edge of a cliff").

"Protagonist" is perfectly good English, but I have not heard the word used much in normal conversation. Usually you would hear the words lead character, principal character, hero, star, etc.

"The woman he was in love with" is how you would normally hear this sentence said. Technically, the grammatically correct way to say it would be "The woman with whom he was in love", but very few people would say it like that in normal conversation.
