The arrival of a letter delayed by 33 years sparks off a quest that leads both on a nostalgic journey back to the 1980s and right to the heart of France today. Middle-aged doctor Alain Massoulier has received a life-changing letter – thirty-three years too late. Lost in the Paris postal system for decades, the letter from Polydor, dated 1983, offers a recording contract to The Holograms, in which Alain played lead guitar.

Overcome by nostalgia, Alain is tempted to track down the members of the group. But in a world where everything and everyone has changed...where could his quest possibly take him?
