Romy (Pom Klementieff), a Parisian DJ on the verge of a great career, comes to the Canary Islands to perform at a nightly techno party. The next morning she wakes up alone in her hotel room: her best friend Chloé has disappeared without a trace. The local police respond with indifference, and the residents respond with silence. The only one who decides to help is Vincent (Benoît Magimel) - the owner of a club with a dark past, whose intentions are impossible to fully read. The search leads Roma from the appearance of a tourist paradise to its disturbing face: underground corridors and shady clubs.
