The Mystery Key 1959

A fussy insurance inspector (Varela Silva) has the mission to investigate why, in three years, 325 employees have passed through a farm shop. In his police demand, he speaks with the maid, the girl Elvira (Fernanda Borsatti) and with the store's boss, Mr. Silva (Henrique Santos). His curiosity will only be satisfied with the arrival of Dona Berta (Elvira Velez), with her "nausea" daughter (Isabel de Castro) and her "unbearable" granddaughter (Guida Maria)
