Romeo, a lovelorn Roman musician in his 40s with 20 years since his only hit, consults a fortuneteller who predicts he'll find love and money with a foreign singer named for a flower. In Brussels he meets Marguerite, an older chanteuse who interprets Jacques Brel and loves her yappy dog. Then, late one night, he's bingeing on burgers when he meets Iris, a 25-year-old waitress, free spirit, poet, and singer who sleeps with a new man every night. Romeo puts her poems to music and they form an act; he moves in with her and pays all the bills. She insists it's business, but he's really falling for her. What will happen when an important producer hears them perform?
