Tomas and Sofia have lived in Montreal a long time, but Sofia is feeling nostalgic. One day they befriend another couple, Luisa and Mariano, recent arrivals here who are feeling adrift. In a moment of desperation, Luis...展开a speaks longingly of the Charuflauta, an apparently curative procedure for the melancholy. Sofia convinces Tomas they should help Luisa and Mariano launch a local Charuflauta business together. Tomas is skeptical - he's the only one who can't remember what the Charuflauta is. Nevertheless, the four start up an agency dedicated to providing this mysterious service. When their first clients, another couple, call them up and actually request the fabled service, a poignant comedy of errors ensues.
