Marga the cat is invited one more year to the poetical tea party organized by her friend Tortell in Sarrià. Tortell wishes to recite a poem by great J.V. Foix, but he has suddenly lost his memory! Marga the cat suspects the gargoyles have something to do with it... The Elephant and the Unicorn are the naughtiest gargoyles of the cathedral of Barcelona, and are always looking for ways to irritate her. This time they have made use of the «forgetfulness Powder» they found in the cathedral. Marga the cat will have to stop them before they use the powders on anyone else. The cat, her friend Barcino and the poet J.V. Foix will live an adventure in the village of Sarrià!
