Posidonia

In 1778 a group of merchants from Genoa became the first settlers on the island of Tabarca. 250 years later, a filmmaker shoots a documentary to discover the secrets of the posidonia, the longest living being on the planet. Everyone thinks it is algae, but it is a plant and produces flowers. The beautiful posidonia bloom should be the ending of the film. But a global pandemic will turn events around. All the islanders have disappeared. And the flowers too. (Seminci - Valladolid International Film Festival)
