Luís Rovisco is a divorced man about to retire from a security systems company. He lives alone with his cat. Although it may seem difficult to make a film with such material, João Nicolau creates nothing less than a musical on wheels, sung by a non-professional actor and mature debutante. Between absurd situations and a dislocated and impassive humor, the last chance of love passes in front of Luís's eyes while modern security boxes and safety gates turn back on him, in a film in which there is room even to evoke the Spanish band Las Ketchup.
