Married couple fleeing war and house keeper

Hi. I watched this movie years ago. There was a couple fleeing war. This couple bought a house from rural. And there were house keeper. Married man didn’t want this house keeper but house keeper stayed at home and opposed them. And then married woman started on a relationship with house keeper. (She had to do this to live) In the end, (i guess because of the war) looters came to house and a fight occured. I think this movie about awareness to be unity for America.
And the housekeeper was a men. I need to write maybe I write wrong because of language differences. And maybe he May not housekeeper but house guard.
Please help me.
