Better Living (1998)

Three grown daughters try to find their own personal ways to deal with their dysfunctional parents. The mother is an unorthodox woman with out-of-the-ordinary ideas, including one where she takes a jackhammer to the basement floor of their house to build a cavern where the family can live better. Their father, an ex-cop, disappeared 15 years earlier and then re-appeared with no explanation and commandeers his wife's project by placing the whole family in a survivalist situation. Jack is the priest-brother to the mother, who is forced to counsel the family despite his own problems with his faith.
