After a tough few years floundering around the British film industry, experimenting with amateur pornography and watching her father's health rapidly decline, Charlie and her best friend Laura journey to her ancestral home of Clipim, an island off the west coast of Ireland. She knows this could be the last chance to connect with her dad's history before she loses him.

But when the girls arrive, Charlie begins to question both her difficult relationship with Laura and her father's childhood stories. Before long, she's embroiled in a devastating conspiracy that's been sixty years in the making...and it's up to her to reveal the truth.
