Looking for a movie

Hi, I don’t remember the title of a movie, I hope you can help me.

The story follows a man, alone in the planet. He met a girl and they felt in love.

I remember 2 things in this movie.

The rat attack scene : they left some meat, so rat attacked the house.

And a groupe of people helping them to dig a well, and they killed the boss of this group.
