Loud rock music is paying at the Château and it's giving Judith a headache. Jeremy's old rock ‘n' roll friend Dura is recording his comeback album in the Millhouse. Jeremy locks him in and leaves him to work alone - but not before insisting on taking a selfie. Outside, in the sound van Dura's wife Mandarina, and Marco, his sound engineer, have just started to record Dura's latest track when they hear him scream. Forcing their way into the Milhouse, the trio find Dura lying dead with a head injury. A strange symbol is drawn on his face. How could he have died in the locked room alone? Caron calls in Jean to try to make sense of it all. At La Couronne, Trevor is meeting Cooper for the first time when Jean receives Caron's call. Dom and Trevor are both huge Dura fans and are horrified to hear that he's been murdered. When Jean and Dom go into Dura's studio, Dom is overwhelmed to see Dura's original speaker and can't help but touch it. Could that be a tear in his eye? Chloe made the lucrative deal with Mandarina for Dura's album. She arrives in Sainte Victoire for the first time to tell Mandarina that the record company are demanding their money back. Mandarina and Marco are outraged and Judith throws Chloe out. That evening Dom is at Jean's house trying to impress her with his collection of original Dura albums. Jean is intrigued and starts to investigate this strange murder. Can Jean and Dom find out what really happened and discover who would want this rock legend dead?

Judith and Jeremy have arranged for their friends to attend a murder mystery night at a hotel with a spooky history. However, matters take a deadly turn when a dead body turns up.
