His Mother's House (1974)

A young man, Petter (Svein Sturla Hungnes) returns home from college during a holiday break to visit his widowed mother (Bente Børsum) breaking up his fiancé, Aud Fosse. Along the way he meets an attractive woman, Eva (Frøydis Armand) and they hit it off so well during his return trip that she accepts an invitation from him to stay at his Mother's house during his stay. But his Mother is not pleased with this surprise as she has rather strong feelings for her own son and desires to keep him all for herself.
