Two girls (Rosa and Rosae) had to be left when they were children, they exchanged a diary and a collar and, mysteriously, their personality; one became writer thanks to the diary and the other became a fortune-teller who gives luck to her lovers.This movie is nearer to the classic 'españolada' than to the new Spanish cinema, there are very few gags which get to make laugh, so it's a boring film; luckily, there aren't cultural jokes (typical of the old Spanish comedies). The lead actresses, the great singer Ana Belén and María Barranco, have done better movies, as well as the director, Fernando Colomo.
