Mussel and Scallop, visitors from Galicia, Spain, are given a tour of Dublin, Ireland by their new friend Molly. Molly shows them many of Dublin's landmarks like O'Connell Bridge, statues of James Joyce and Oscar Wilde, Dublin Castle, Trinity College and its Long Room containing ancient manuscripts. She explains aspects of Irish culture like pubs, music, and Gaelic language. By the end of the tour, Mussel and Scallop are tired and thirsty, so Molly leaves them to get refreshments at a cafe before returning to her Irish dance class.
