As kids, Emily and Chess were inseparable. But by their 30s, their bond has been strained by the demands of their adult lives. So when Chess suggests a girls trip to Italy, Emily jumps at the chance to reconnect with her best friend. Villa Aestas in Orvieto is a high-end holiday home now, but in 1974, it was known as Villa Rosato and rented for the summer by a notorious rock star, Noel Gordon. In an attempt to reignite his creative spark, Noel invites up-and-coming musician Pierce Sheldon to join him, as well as Pierce’s girlfriend, Mari, and her stepsister, Lara. But he also sets in motion a chain of events that leads to Mari writing one of the greatest horror novels of all time, Lara composing a platinum album --- and ends in Pierce’s brutal murder.
