The second movie from director Abel Ferry which takes place in high mountain after High Lane (2009).
When the film first aired in France, the end credits were sped up, leading to a 1 hour 28 minutes and 21 seconds running time and a truncated end credits song. However when it was rebroadcast on November 10th 2017, the end credits were left intact with the film now running for 1 hour 29 minutes and 5 seconds and the end credits song playing in its entirety.
The extra wide 2.35:1 aspect ratio is uncommon for TV productions, which tend to favor the 1.78:1 ratio that fits squarely in standard widescreen TVs.
