Strange Voyage

Paquita (Rafaela Aparicio) and her brother Venancio (Jesús Franco) are both unmarried and still behave like children, and all they want is to get out from under their older sister. That sister is Ignacia (Tota Alba), a grumpy old maid who runs the house in a small town near Madrid. Fernando Fernán Gómez sets the three of them together under one roof, and the one thing at risk is whether the house can go on belonging to Ignacia.
