The poem tells how Mireille's parents wish her to marry a Provençal landowner, but she falls in love with a poor basket maker named Vincent, who loves her as well. After rejecting three rich suitors, a desperate Mireille, driven by the refusal of her parents to let her marry Vincent, runs off to Saintes-Maries-de-la-Mer to pray to the patrons of Provence to change her parents' minds. Having forgotten to bring a hat, she falls victim to the heat, dying in Vincent's arms under the gaze of her parents.
