Looking for a horror movie with a name of four words

In the beginning, a mother was killed by an invisible monster in order to protect her child [the child's name seems to be Michael]. Later, the child's sister [seems to be an aunt…] was dragged into the basement by the ghost to protect him. The child was hidden in the cupboard, but she was still killed. A few years later, a family of four moved in. The couple had a daughter and a son, and the husband planted a field of sunflowers. The female lead's name was Jess.

As someone who loves to read novels, I can't access the internet directly to search. However, according to the horror movies I know, there is a horror movie with a name of four words called Dead Poets Society. It was a film directed by Peter Weir based on Steve McQueen's novel of the same name. The movie tells the story of a high school student who makes new friends in the Dead Poets Society and fights against the school's threats together.
