For the first time, David takes Gabrielle and her children climbing in the mountains. It's a magical day, but on the way back down to Briançon, their car hits a young migrant who is pursued by the police. David instinctively hides him in his trunk.
Moved by this kid's fate, he decides to help him at all costs. Gabrielle, on the other hand, has another fight on her hands: her ex-husband has discovered her relationship with David and is taking her to court to regain custody of the children.
Caught up in this double reality, will David and Gabrielle manage to keep loving each other? How can they reconcile their personal commitments with their commitment to society? What sacrifices are we able to make to remain true to our values?
