Paris, 1941. A family of scientists is on the brink of discovering a
powerful longevity serum
when all of a sudden a mysterious force abducts them, leaving their young
daughter April
behind. Ten years later, April (Academy Award winner Marion Cotillard) lives
alone with her
cat, Darwin, and carries on her family's research in secret. But she soon finds
herself at the
center of a shadowy and far-reaching conspiracy, and on the run from government
agents,
bicycle-powered dirigibles and cyborg rat spies.
