Marc Riso is an actor who appeared in "The Deep Dark," "Start Over," and "Notre tout petit petit mariage."
Oligarch Jean-François is tired of his spoilt son Louis' behaviour and organises a scheme to make him believe that he has travelled back in time to the Russian Empire in 1860.
Marc, a surgeon at a hospital, is murdered on December 31. When his ex-wife, best friend and a police lieutenant find themselves stuck in the same elevator, they emerge from it and realise they have moved a year back in time.
