It is winter in Seville, nevertheless it is hot. Ignacio and Lydia decide to go around the Andalusia seaside to look for the real effects of the climate change that are taking place on their Autonomous Community, particularly on Doñana National Park. During their route they will meet Maria and Diego, two friends who will go with them on their discovery about the effects of the global warming on the andalusian wetlands. Together they will have the opportunity to interview two experts in biodiversity and climate change.
