It’s off-season, so the resort is mostly deserted, except for a few residents and a handful of staff charged with sprucing up the place. Ruth gradually settles into her new environment, finding work and making a new friend in the form of make-up enthusiast Jade. But one afternoon, while giving Tom’s caravan a spring clean, Ruth finds evidence her beau might be cheating on her. As her desire to uncover the truth turns into an obsession, she begins to realise she might be looking for something else entirely.
