Isabelle has a cunning scheme to escape her family's first-marriage curse: all she has to do is find a dupe to seduce, marry and divorce, then marry the man she loves. The plan would be foolproof if the mark wasn't the intolerable Jean-Yves Berthier, travel guidebook writer, who Isabelle winds up following from Kilimanjaro to Moscow. It's one wild honeymoon - for better and, especially, for worse.
