Drie gezinnen leven in evenveel appartementen in hetzelfde appartementencomplex. Op de eerste etage woont een jong koppel dat een sterk vermoeden heeft dat hun oudere buren hun dochter mishandelt. Een verdieping hoger oefent een hardwerkende man zijn beroep uit waardoor zijn echtgenote zich over hun twee kinderen ontfermt. Terwijl zij tegen de eenzaamheid vecht balanceert ze op de rand van de krankzinnigheid. Boven haar woont een gepensioneerde rechter en weduwe die haar verleden overpeinst.
