An apprentice tightrope walker at the National Circus School, Evelyn finds herself drawn to the archaeological dig going on in the basement. There, she comes across a skeleton wearing a locket that is identical to her own. Could this have something to do with the secret surrounding her mysterious ancestor Élisabeth Chénier? One turn of the key in the locket and Evelyn finds herself projected backwards in time and menaced by a gang of bandits. (Films in French, useful for teaching French as a Second Language.)
