Carlo, a graduate student, is writing his thesis on a deceased B-movie director. His research leads him to his late father’s old villa, where he hopes to uncover the truth behind his mother’s mysterious death in a car accident years prior. While digging through scripts and archives, he meets Emma, a woman who claims to be his sister but quickly initiates a seductive and disturbing game with him. As Carlo's investigation into his father's "vices" and the scummy side of the film industry deepens, he finds himself trapped in a web of incestuous attraction and lethal family secrets that his father tried to bury.
