Lily Johansson returns to Paris, the city that broke her heart and destroyed her ballet career, hoping to ease the guilt over her fiancé's death and to make amends with her estranged sister Natalie, a ballerina with the Boheme Ballet. Terrified of loving again, Lily nevertheless finds herself becoming entangled with the driven composer Yves Rousseau. Lily has many reasons for keeping Yves at arm's length but as he recounts the colour, drama and intensity of the Ballets Russes in 1917, the magic of this Bohemian era ignites a spark within her. Meanwhile, cast in the role of honouring Ballet Russes dancer Viktoriya Budian, Lily's sister Natalie develops an unhealthy obsession. Natalie's behaviour becomes increasingly erratic as elements of Viktoriya's tragic life resonate in her own. Lily fears for her sister's safety and sanity so when Natalie goes missing, she and Yves set out on a desperate quest across France to find her and, along the way, battle their own demons. Could the search for her sister, lead Lily to realise that ballet—like love and life—should not be abandoned so easily?
