An adaptation of cult author Deborah Levy's unique and provocative novel about love, loss and longing. A woman invites a naked stranger found floating in the pool of her family holiday villa to help her set those she loves free.

When a family arrives at their villa in a remote coastal village, they find a stranger floating in their swimming pool. The mysterious woman with green fingernails claims to be a botanist and her lingering presence comes to emphasise the distance that already exists between the parents, war-correspondent Isabel and melancholic poet Joe. Tensions mount, temperatures rise and a perfect vacation transforms into a perilous spectacle, magnified by the beauty of the landscape that it erupts across.
