Eva (Eugénie Derouand, Paris Police 1900), an
ex-dancer, is now using a wheelchair, unable to walk. When her friend
Sophie (Honorine Magnier, Tomorrow is Ours) gives
her an old wooden antique advent calendar before Christmas, she realises
each window contains a surprise that triggers repercussions in real life.
Some of them are good, but most of them are bad, really bad. Now Eva will
have to choose between getting rid of the calendar or walking again – even
if it causes death and destruction to everyone she holds dear around her.
