'Schaffa, Schaffa, Hüsl Baua' Teil 3 - Mei Home isch mei Kaschtl

27 years after building their house, 5 years after paying off all debts, 2 years after the last child moved out, and a life of togetherness, fate strikes cruelly for Günther and Irene Batlogg:
Daughter Laura wants to return home to Frastanz with her American husband and children.
Their goal: Günther's house, which is to be converted into a three-generation home.
Can the head of the household fend off the hostile takeover?
Especially since he soon has an opponent in his own four walls, who is very taken with this idea.
