Little House on the Prairie (1974)

Nels Oleson has had it up to here with Harriet's snobbish, meddlesome behaviour, particularly toward the Ingalls family. Mrs Oleson doesn't take kindly to her husband's old-school beliefs, either. The two get into a huge argument and decide to separate. This sends the Ingalls' and the Olesons' other friends to intervene and convince them to settle their differences.
