Julia Fearon arrives in Spain with fiancé Charlie and their 18-month old son Haydn, excited to meet his family and plan their forthcoming wedding. But Julia's happiness is short-lived as she must grapple with a clan steeped in tradition, ritual and Catholicism. Unable to communicate, she becomes increasingly isolated and soon, lies from her past start to unravel, threatening her present. But shortly, domestic strife becomes the very least of her concerns when a day at the beach leads to a terrible tragedy. A freak storm causes chaos and amidst the pandemonium Haydn disappears. Whilst the authorities presume him drowned, Julia is tortured by the possibility that her child is alive - and has been snatched. Grief-stricken, Julia's world narrows to a desperate search to find the truth, following every lead she can, whilst surgeon Charlie throws himself into his work in an effort to return to some normality. Soon, the cracks between Julia and Charlie threaten to engulf them both. Consumed by the fact that they may never know what happened that day, can Julia find the peace within her to let Haydn go? Or will her faith be rewarded with the truth?
