New York, 8am. Alice, a young Parisian cop and Gabriel, American jazz pianist, wake up on a bench in Central park hand­cuffed to one another. They don’t know each other and have no memory of having met. The night before, Alice was at a party with her girl­friends on the Champs-ElysÔees and Gabriel was playing piano in a club in Dublin. Impossible? And yet… So many ques­tions leave them con­founded. How did they get them­selves into such a dan­gerous sit­u­a­tion? Whose blood has stained Alice’s shirt? Why is one bullet missing from her gun?
