On her twenty-first birthday, environmental activist Alice learns that the man who has raised her is not her father after all. She is surprised to learn that her biological father, William, is a property developer based in Ibiza, where he is immersed in a huge deal that will further increase his wealth. Alice and William meet for the first time in Ibiza, inadvertently finding themselves on a road trip across the island, unravelling secrets from the past and glimpses of the future as they go. Seen from the perspective of four characters with widely divergent world views, Lost in Ibiza offers an intimate meditation on family dynamics, set against the larger canvas of an island utopia that teeters on the brink of environmental catastrophe.
