Between Two Worlds

I'm still thinking about this movie...

Juliette Binoche stars as Marianne Winckler, an author and journalist who goes undercover with the goal of exposing the plight of workers in Northern France.  When she is hired for the grueling job of cross channel ferry cleaning, she forms close friendships with the cleaners knowing that there will be a time when she will need to tell them the truth about her identity.
