A young woman taking care of her diabetic father gets involved in a one way relationship. Portrait of a generation about to replace another, Demain is a film based on an inertia marked youth, and on it's precursors confronted to their own disappearance.

Myriam Monette, a not very conformist and slightly whimsical Miss Weatherwoman, is now forty years old, has a new boyfriend and a new mandate at Channel Météo (also called Channel M). On the surface, nothing has changed. In reality, nothing is the same anymore. Like a green lawn on a summer day suddenly covered in snow, Myriam went to bed a confirmed single “adulteen” and woke up in love, living with someone else and undergoing major changes.
